i think they are all pretty good these days, i ve heard the linksys is the best if u want an idiot proof setup, i recently got 2 netgear 54MBS 614G wireless routers and they work flawlessly.
I would match brands with whatever router you have because many times they have some 'speed acceleration' features between the router and the network cards if they are the same brand. Otherwise, just get whatever is on sale.
