Looking for 3000gt ECU can anyone help???

I am looking for a ECU for a 3000gt '92. I am going through alot of crap with the dealer and I have looked up and down for one and cant seem to come across one. Anyone have any info on where to go to find one????? any help will be much appreciated. Thanks!

Again... Check 3SI.org and find a part out... Damn we should have a sticky thread titled "When in Need of a Part Check 3SI!"
