I just bought the Netgear MR814 and one of their USB devices, the router was $99 and had a $30 rebate on it, the USB thingy was I believe $49 with a $20 rebate on it. Those rebates and prices changed a week or two ago (got in on the last day), but check Microwarehouse, I know they have the router for $109 with a $30 rebate, the adapter for $60 with a $10 rebate, not sure if the other stores are offering it anymore.
Computers4sure.com is offering the router (again the 814, four hard wire ports, wireless, and a port for your cable or dsl internet) and a PCMCIA card for $140, the router alone same as microwarehouse.
Watch for the rebates as the new stuff is about to roll out, there are some very good deals out there. I went with the Netgear because over in the forum for my DSL service in
www.dslreports.com everybody who had it said it was a breeze to set up and use, but there are certainly other brands out there (though I would always start at DSL reports and ask for what works for your service, chances there are many people there doing it already).
