Linksys WRT54G...big sub-sid of Cisco...can't go wrong.
If you can (and if you're interested), get a version 3 (old) as this has larger firmware ROM of 8MB and you can hack it if you want to.
I have a v5 (2MB ROM), and it's fine. I think they're up to V8 now...not sure.
They're not expensive and have good security features.
