i would buy one from hmotorsonline.com or one of those reputable sites... if you're gonna swap out your tranny anyway, id recommend getting a 5 speed.

you're gonna need a load of parts... ecu, pedal set, clutch/flywheel, clutch booster (do they call it that?) and tranny... shift linkage, shifter, shiftknob, center console. i have some of the parts (ECU, pedals, shifter & knob) id be willing to sell you, ill meet you halfway... so we each drive about an hour. that might save you some cash...
