Also, an evaporator core should only cost around $350 or so max, not $900...

Sorry...that was a quote I got for replacing a Jaguar evap...got my wires crossed there.
I'm probably wrong about the aluminum too...it's just that we had a house unit with an aluminum evaporator that also went south prematurely...so I'm not fond of aluminum units for that purpose...
