In Dash LCD/DVD/CD/CDRW/CD/MP3

Alright, most of the in dash lcd/dvd/cd/mp3 and so on things cost over 800 dollars on ebay alone. My first question is, is there somewhere to get it cheaper? My next question is, is there somewhere that you can get the dvd/lcd/cd/mp3 etc but without touch screen technology (because I assume it will be cheaper without it) ? Another question is, if I get a DVD/CD/MP3 deck and then a flip out LCD deck, as in separate, not all in one, will it even fit in my dash? Lastly, is Pyle really all that bad? I really just want a DVD/LCD/CD/CDR/CDRW/MP3 compatibility in my dash for under 450 dollars, I dont care what brand. Can anyone help out? Thanks for info.
