What budget torque converter?

Why do all converter discussions go from "don't care" to "$700" in under 12 seconds? 95% of the folks on this site would be happy with a stock 340 converter. But lots of guys have full size converters in their Dusters and wonder why their car is doggy. The problem as I see it..... Stock hi-stall 340 convertersa are NLA. Anybody know a source? Or even a hi-stall Dodge truck converter? Ones they put behind small blocks in low-geared trucks? Places like O'Reilleys used to have them for under $100.
