I have heard mixed reviwes of Eclipse Amps. My friend has a two channel one right now and the high-pass filter is HORRIBLE and sounds like shit. It only 3 months old.

As for Amps, I am currently running an Orion 6002 for my e12a and an Avionixx 440.4 and have been pleased with both.

An amp on ebay should really be too much of a problem.
