Hello. I would like to buy a wifi antenna with the greatest signal
strength for the lowest cost. I found some 24 dbi for 50 dollars. If
you know of a better deal, please let me know. Thanks in advance.

Cheap, powerful, good -- pick (at most) two.
RadioLabs has a good parabolic dish antenna for $70
<http://www.radiolabs.com/products/antennas/2.4gig/2.4-aluminum-parabolic.php>
Do you really need that much gain?
Can you live with the narrow beam angle?
You can get up to about 15 dBi gain with a simple build-it-yourself
"cantenna" for only a few dollars. Google "wi-fi cantenna".

to be used where, how, as AP or Client ?
directional or omni ? what are you aiming at ?
how far is the electronics - ie, cable length ?
inside or outside ?
mounting issues ?
path issues - trees, buildings, etc ?

Has to be directional for anything close to that gain.

Good point -- lots of signal can be lost on a cable run.

An antenna can not be 'powerful', nor can a speaker.

Powerful = higher gain.

Based upon the lack of specifics in my original question, I decided to
revise it.
I would like to buy a wifi directional antenna for my computer's nic
card. It should have a high gain for a low cost. I would prefer an
indoor antenna but an outdoor is fine. The connector is a SMA and the
cord only needs to be a few feet. I found some 24 dbi for 50
dollars. If you know of a better deal, please let me know. Thanks in
advance.

Hi. That helps, but it's best if you give an indication of the
situation that you intend to use it for.
All too often somebody looking for the highest gain, has no clue as to
how much gain they actually need and are trying to buy a laser when
what they really need is a flashlight.
Is the AP (presumed) you are connecting to far away? Do you
understand the tradeoffs of using something as precise as a 24 dbi
antenna? How hard it will be to aim for closer sources? That the
mount should be well fixed ?
Unless the post begins with - I'm doing a 1(or more) kilometer link
and ......- I think that high of gain would not be appropriate for
most circumstances that an amateur would find themselves in. More
likely you want a 10-14 dbi panel or backfire antenna.

The distance is from my house to my brother's house which is one
block away.

Yes. I would have to aim it at his house with about a 8 degrees
margin of error. That should not be much of a problem.
>*That the mount should be well fixed ?
I was hoping to get an antenna that could be used on a small
portable mount on my patio or inside the house.

Actually, I am currently using an Airlink 10 dBi antenna, but my
connection speed is between 2 and 5.5 Mbps rather than 54 Mbps. It is
a weak signal.

I'm of course talking just horizontal, as I would hope you know.
Calling high-gain "omni" antennas "directional" would be confusing.

Then all you probably need is 15-16 dBi, especially since a directional
antenna might help by rejecting interference that might now be a
problem.
Build it yourself for under $10:
<http://www.instructables.com/id/10--WIFI-16dBi-Super-Antenna-Pictorial/>
Or try a cantenna, as I suggested before, which also might be enough.
$32 for 15 dBi parabolic grid (unknown quality):

If the focal point of that antenna is about two feet from the rotation
point, You must push it two inches to one side before you have a 3dB
loss. Why don't you believe he is able to put it up with such a steady
precision?
His problem is obviously not signal strength, but multipath and
absorption, unless the definition of "a block" has increased much
lately. He doesn't need more power, but clear 0.6 frensnel zone line
of sight. On the other hand, if he in fact put up a 24 dBi antenna,
assuming his card gives him 20 dBm and cable and plugs are -2 dB, his
electron current will let him burn sausages in the beam at 16 Watt.
Those sausages he can sell for money, buying himself a regular p2p.

OK. You know what's up. Still, the 10dBi really should work fine
over such a short distance - with clear line of sight, so I'm
imagining that the real issue is that you are trying to punch through
trees or something or else, as ChrisJoy says, you don't have a clear
fresnel zone.
Or, you've got some significant cable loss going on with your 10dbi,
such that you're only getting 5-6 dbi effective.

Really, one of those Ubiquiti Nano LoCos will be perfect. Any antenna
plus good cable plus pigtail will cost more and you will be more
limited on length.
Just mount the LoCo2 as high and clear LOS as possible and run an
cheap ethernet cable inside to your pc or router. It will come with a
power injector.
It may hurt to abandon your wireless NIC in the desktop, but you'll
get over it. The loco will act as the radio and the antenna.
