I've seen enough of those low buck converters apart to tell you one thing: You get exactly what you pay for. NEVER let price be your guide when purchasing a high stall. Email, call some of the companies mentioned in this post, and many other posts regarding high stall converters. Ask people that have purchased their product what their experience has been with the company they bought it from, and if there where any issues, how did they handle it. The company that I worked for in the past had a 1 year warranty on all high stall converters, and on the hard core race units, they had a two year warranty. Each converter was issued a serial number so that in the event it was returned for any rework as requested by the customer, we could keep a record of what had been done to it.
