Hi Mike,

In general if you are using the basic 18" dish, all receivers are basically compatible. However, you should consider utilizing the new 24" elliptical dish if your system hasn't been installed yet, it allows you to receive hdtv, and if you are in a lower tier market, will be required for local.

A note: with the new dtc100 from rca, most current dss receivers are not compatible with the included multiswitch which allows you to run 4 receivers. The only unit I've found that works with this switch currently is the hughes. All new models that are rolling out should be ok though.

Anyway, that's it for now>
