Best modem just for Internet

[SLAWTERX]

Hi, I need to buy a modem for my house by tomorrow which is when the installation guys come in and I want to know what the best modem would be for Comcasts Performance with Blast! service. I don't have cable or anything else, just internet so I want to know if that makes a difference in which modem I should buy and which one will give me the best bang for my buck!

Shouldn't matter too much. Just make sure you get one that supports DOCSIS 3 if you want the maximum speeds that comcast offers.
