f4zf-12a650-jb looking for/wtb

have a 94 cobra and the ECM/PCU went out on it. I cant seem to locate any aside from the one('s) listed on Ebay... i'd rather not go through that seeing as i could end up with something that doesn't even work, and be out $350. So, if anyone knows where I'd be able to locate/purchase/trade one, or if anyone on here has one for sale. it has to be a JB, nothing else will do.

I hope someone has some sort of information. Thank you for your replies, and I hoped i posted this in the right area.
