Personally I think that supplying the connectors and possible the drivers will be a great deal more cost than the $22.00 shield and 3.2" tft display sold by Electrogragon. The 3.2 display is made by Itead and I have 2 of them in front of me working perfectly, a 2.4" and a 3.2" 65K color display and the library UTFT by Henning Karlsen works very well with both. I have some years of electronics experience and I wouldn't attempt it... Not without a Kit of parts and clear instruction.
