im looking for a new headunit, specifically one with a screen. Im going to be buying off of ebay so i want to know what you guys would recommend, i want a nice looking unit but one that will sound great too, also i am getting two headrest monitors so im going to need one that i can hook those up to. The max I'm looking to spend is 600 without shipping on ebay so if someone can find me something good that would be great, i was looking at the pioneer avh-p5700dvd is that good or can i get something better for around that price?
