Good place to buy cable modem?

Hello again,

I want to find a cable modem that works with Cable One, they support:

3Com Home Connect Cable Modem External (3CR29220)
3Com Office Connect Cable Modem External (3CR29210)
3Com Home Connect Cable Modem External with USB (3CR29223)
Motorola "General Instruments" SURFboard (SB3100)
Toshiba PCX1100

Are there any good alternatives, inexpensive or otherwise? Should I
stay with the recommended list above? Any good sources?

Thanks,

Armand a.k.a. Bucky in Prescott Valley
