That's kinda like asking which is your favorite child..you will get a lot of different responses..

so

I like Linksys stuff.

 I run a WRT54G

I run the "G" stuff. I would say shy away from the N equipment untill the spec is fully approved as there is too much variance in equipment.

Hi

I used Linksys and have no problems with it.

Depends on your technology comfort level, but I recommend something that can run dd-wrt (www.dd-wrt.com) or other 3rd party firmware.

I'd also go with 802.11g equipment for now.

Here's another vote for the Linksys WRT54G.  No need for the "S" version of that router, IMO.

I wish I had a dolalr for everytime I recommneded that router.  Actually, bought another one on NewEgg yesterday for $39.99 with free shipping.
