said by maartena: but I haven't seen a DOCSIS 3.0 modem yet for under $80 or so, and the decent ones cost a little more.
If you rent the modem, and DOCSIS 3.0 comes to your town.... swapping the modem is free. If it breaks, even if it is your own fault by spilling a drink all over it..... replacement is free.
It's give or take I suppose.... $5 a month nets you $60 a year, and if you buy a $80 DOCSIS 3.0 modem that is going to last 3 years you have made your money.
Prices on a SB6120, a Docsis 3 CM, run from $75 to about $100 at many online stores. Plus the cost of shipping and taxes in some states.
