I am in the process of switching from AT&T DSL to Charter Cable and need to purchase a DOCSIS 3.0 Cable Modem.

Charter want to shaft me and charge me $10/month to "lease" a modem, when it makes more sense to buy one. The question is, what modem should I buy?

I am looking at the Charter "Plus" package which has speeds of 30Mbps/4Mbps.

I already have a router for my wireless and home network connectivity so all I need is a DOCSIS 3.0 compliant cable modem.

Suggestions, recommendations?
