Netgear Rangemax vs Linksys WRT54GS or even WRT54G (3rd party firmware)???

Just about to replace my wireless piece of junk TP-Link WR641G with so called 108M speed

I'm looking at the Rangemax expensive but with lots of features, good range and speed? Will this work with any 108M PCI card?

And of course the Linksys WRT54GS and G which are upgradable with 3rd party firmware

So I'm trying to decide which one to go for the WRT54G or the WRT54GS (obviously not v.5 from what i've just read) But if i get my hands on a v1 - v4 WRT54G can i make it as fast as the GS ?(which firmware) will that enable the G to work with 108M cards or won't the GS even work at those speeds...

I understand that the GS version has more flash/ram then G version....how will that really affect me

Also I use alot of P2P most routers crap out after a while these apparently do not???? And looking to stream video from one pc to another

Purely looking at these for the 3rd party firmware possibilties...

But Netgear Rangemax also looks pretty cool or is that crap?

Hope to get some answers...thanks

prices are where i live are WRT54G about 50 Euro
WRT54GS about 85 Euro
Rangemax about 120 Euro

I would go with the linksys routers, because of its expandability. Specially because they are linux based you can do so much with them. The wrt54g has a firmware that makes it work at 108mbs. The problem of this one is that it uses so much of it memory, that it tends to slack a little.
In other words the best choice is the wrt54gs. And the best firmware I've played with is the one from SVEASOFT. They have the best firmware I've seen so far.
