I actually just got the WHR HP G54 on Jack's advice =P. DD-WRT was a piece of cake to setup (Although I'm relatively proficient with computers and linux).
Anyways, the range is pretty good, almost double of my old router. Stability seems fine, and I love the logging options + other features. I can get about 40 meters in a building with cinder block walls every 4 meters. Residence =S.
Anyways, I really suggest this one as well. So far there's been no problems at all and I've already discovered one of my friend's installations was compromised using the logging features.
