The suggestion for Eclipse is a good one. But Pioneer's higher end stuff isnt junk either. Just because its sold in walmart doesnt mean they dont make some pretty good stuff. Like the no longer available DEH-800PRS and DEH-880PRS, along with the DEH-P99RS. Those 3 head units are considered some of the best in the SQ world.. And guess who they are made by? Pioneer...

Now, Im not saying the linked version is there higher end stuff, but just wanted to point out they have some decent stuff out there.
