Home Depot carries cheap terminators, also.



Amplifier:

The amp that I have is good, but it's not great and it's getting pretty old. I'll post more information on it when I have an opportunity to dig up the specs.

Motorola currently offers a bi-directional amp that boosts both data and video signals (up to 1 GHz). They're available at Circuit City for $80, but your cable company might be able to send you one for free,

Other:

Keep cable runs short by trimming excess cable and crimping on connectors yourself (don't use cheap screw on connectors).
