Hi! I can see there's many hardware versions of WRT54GS - the newest seemes to be V4 (but there's not much information about it). Which version should I buy? I've read, that V4 has less memory than older models - this doesn't sound too good. Which version should I be looking for? I've planning to run third party firmware (but haven't chosen which one yet). I've read the autopsy, but this doesn't cover V4 yet - and by the way, it looks like alot of information is missing in the quich charts.
