it's been a better price before, but i'm obviously nitpicking. this is a good price for DOCSIS 3.0  

Paid $82 for this 2 years ago.
Newer model is 6141 for $82.

Yeah I saw that its been a little bit cheaper before but for anyone that wants one now I figured this was a pretty good deal.

I was just at WM to pick one up at this price, and they are almost $75 in store. Good get - I was wrong. GREEN! Thx!

Hey your welcome. I've been looking to get a cable modem for a while because TWC charges me $4.00 a month to rent mine.
