If I had to, Linksys would be my choice. However, I'm currently running a wired network, and won't switch over until the 'N' standard has been approved for by the standard's committee, (which should happen soon if it hasn't already), and the companies, start releasing FULL 'N' standard wireless routers, and not 'N Draft' ones.
They say the draft ones can be updated, but I'm not getting that trusting feeling from the router companies, myself.
Make sure that if you do get a wireless router, use WPA for your security and don't count on WEP as it's easily compromised.
