I hope this belongs here. Does anyone know where I can purchase a cheap router?

Please define the word "cheap."

Also, what kind of router do you want? Wireless, wired, etc.

D-Link Wireless Router from Newegg for $39 (http://www.newegg.com/app/ViewProductDesc.asp?description=33-127-125&depa=0)

One of the more popular LINKSYS routers (http://www.newegg.com/app/ViewProductDesc.asp?description=33-124-151&depa=0)

Just a few to get you started.

Cheers!
