Why did you say i will lose the speed? i'm on RCA DCM425 DOCSIS 1 modem that time warner provided for $2.50 per month.
Like I said, you'll probably lose Power Boost if you switch to a D3 modem. »[TWC] No more perboost?
A quick Googling shows that's actually a DOCSIS 2 modem.
As for rent vs buy, that's all up to you. I personally just bought a SB6141 even though they're not charging me a rental fee as I'm not getting Power Boost as it is and am planning on upgrading to the 30/5 "Extreme" tier soon and didn't want their crappy all-in-one gateway they insist on providing.
