Thanks papa, knowing where to look is half the battle

. I located one locally through car-part.com for $100 Canadian, that's about US$37.65
Made the 50km drive to the scrap yard to pick it up at lunchtime. When the guy behind the counter proudly presented me with the ECU my heart sank. Anyway, he assured me that the donor vehicle was still in the yard and sure enough he took me straight to it. It had taken a bit of a beating on the passenger side and the mounting bracket was a bit twisted but the TCM itself is undamaged.
Still interested in trying the alternatives also e.g. the 03 Ram if I can pick one up sub $100.
