No. Range extenders or store and forward repeaters are a crap shoot
and often don't work. Search for "range extender" or "repeater" in
this newsgroups for all the "it doesn't work" horror stories.
Even if they did work, they have the same speed reduction issue as the
WDS bridge protocol, which is also simplex store and forward.
Be advised that the speed reduction is not as horrible as it sounds.
Let's say you get a 24Mbit/sec connection between the two WRT54G
routers. That will yield about 12Mbits/sec thruput to a wired
computah plugged into the 2nd WRT54G. If your wireless client now
connects to the 2nd WRT54G and gets the same 24Mbit/sec connection,
you will see half again or 6Mbits/sec thruput. However, if your DSL
connection is only 1.5Mbits/sec, the 12Mbits/sec is kinda wasted as
your 1.5Mbits/sec maximum speed will be limited by the DSL and not by
the wireless. As long as your wireless connections are faster than
1.5Mbits/sec x 2 for overhead and x 2 for WDS = 6 Mbits/sec
then your wireless will not slow you down.
You can use WDS to infinitely extend the range, but each hop again
cuts the speed in half. Eventually, you run out of speed. That's
roughly why I thing mesh networks, with routinely do multiple store
and forward wireless hops, are a bad idea.

is worth reading so you know what you're getting into with WDS.
