Sorry, can't say I have, apart from some mentions here and there, and don't even remember if they were positive. What are they offering you? Warranty? improvements? updates?.
My dad got a jasper transmission in his 97 dodge ram. He loves it, 50,000 mile 3 year warranty, paid labor if something happens, towing, and rental car. Everyone else I know who has dealt with Jasper has had a good experience.
