Hey Chris,
what kind of layout are you looking for? all in one "din" unit? or a drop down screen with seperate units? the all in one unit is very costly( as mush as 4000$) but real cool... the screen, dvd and radio all clarion should be around 1200-1500$
IMHO.. I think the clarion stuff is probably the best, good support, good quality, and fair pricing...
