Your cost per bandwidth means you are definitely getting ripped off!
I'm using a POS Netgear wireless router, and Microserve wireless internet with decent results, at about $49:
Better than the cable internet that cost me twice as much. Plus, this is unlimited so I don't have to worry watching netflix.
Wireless internet has come a long ways, if that's available in your area check it out.
I pay $85 for this!
sucks.
