Micro Center in stores and online has the SMC7004VWBR wireless cable/DSL router for $30 after a $20 rebate. This router is a fairly good name brand, and considering it's $30, this is a really hot deal. It's a standard 802.11b 11Mbps wireless router, and I've installed one of these at a neighbor's house with no problem. Very hot deal!
