Just surfed www.overstock.com and found the following:

Crown CE4000 power amp $1013.00
Crown CE1000A3 power amp $417.00
Alesis RA 500 power amp $298.00
Alesis RA300 $224.00

Is anyone familiar with these amps?

I know Crown used to be highly regarded, are they still well thought of?
Alesis is a company I know I've heard of and thought they went out of
business, can't remember much about what sort of quality.
