If you shop based on your criteria of price under 400 bucks, just go ahead and get the most rock bottom "reman" converter you can lay your hands on, because it will not be a good one. Do a search. There are literally hundreds of threads on this.
I have a stock 11in converter that was rebuilt and increased stall to 2500 for about 200 bucks. Worked pretty well for a street driver. I'm not a magician with the transmission sooo, the difference between that one and my new 3500 tight tc isnt to drastic..
