Rottie, the WRT54Gv3 and WRT54GS v2.1(?) just add a button, which causes the software to do some stuff to automagically generate and share a WPA-PSK. It's designed for those users who are too novice to configure WPA-PSK correctly on their own. (Which should be easy, except, well, if you're using WIndows...). Otherwise they're the same unit.
The WRT54GX has a different radio, I believe it's not supported by the hacked firmware yet.
The WRT54GC is a totally different platform, not compatible with the hacked firmware.
Sam's Club has great pricing on the WRT54G & GS, btw.
