The rebuild lasting 100K wouldn't bother me. Not being able to pay for it is the problem. If the 80 is cheaper, it's cheaper.
Well that's really my point, buying a 4t80 from a junkyard would definitely be cheaper than doing a proper rebuild on your current trans. The problem is paying someone to do the custom work to make it fit and tune it is going to increase the cost way beyond just doing a rebuild on your current trans. You also add the unknown of a used trans.
Sounds like you're cheapest option will be to either save to rebuild your current trans or just scrap the car when it blows. Certainly some 4t65 make it to 200k and slightly beyond, but you're definitely coming up on the end.
