Well its cost me so far about 800 including the screen (lilli) i dont have a dvd burner, gps, xm radio, or am/fm radio yet, so i think it'll be more closer to 1300 by the time im done, its well worth it though.
I think the more RIGHT you do it, the more its gonna cost. I'd rather pay more for a tits setup.
oh and yes, this site is awesome, definitely would have cost alot more if it wasnt for the wealth of knowledge this site has to offer, leave all the trial and error to someone else.. That'll save you money. This website has enabled me to build my carputer the first time, right.
