Converter for supercharged truck

Truck has a 4L80E behind a 6.0L that makes 500+ rwhp. 3.73 rear. Recommendation from a guy who's opinion I respect tremendously said go with a Yank 2600. I was shocked, putting it mildly, to find out the converter sells for $900 + shipping. Back in my younger days, $900 would buy a well built turbo 400 tranny with converter. Shooooot. Is there a less expensive way to accomplish what I'm after? Your thoughts appreciated.
Old school at this end also. Why change it? If it's not broke, don't fix it. I'm building a forged 6.0l and planning up turning up the boost to about 15psi. I'm going to run with a stock 4L80E converter.

ditto. i am considering a lower stall speed converter, because of all that power below stall is being wasted. my truck would need big slicks and other traction aids to take advantage of more stall speed. it spins bad enough with the stock 'verter.

I have had PI's and Yanks in my 60's and never had the first issue with either other than the PI being a hair too loose. I just picked up my new Circle-D 258mm 80E converter yesterday. And they do offer one that's not over $1K... But its not the multi-disk bad boy, its a single, after seeing the guts of the single disk I wouldn't be scared of it

All convertors for OD trannies seem expensive. They cost more if retaining the overdrive.
If you are running a stock 4L80E converter with 500WHP, I bet you are already seeing close to 2600 stall with the stock converter. I've ran into many posts with people running the stock 4L80E converter w/FI and getting great results and durability.

Just talked to Chris at Circle D. They do make a 2800 stall speed single disc converter that's quite a bit under $1k. He said as long as there wasn't a full throttle lock up, it would be fine. I'm guessing there is no lock up under full throttle? Maybe for a dyno run, but under normal circumstances, does the converter lock up under full throttle?
