There are a lot of guys having getting good results with his stuff. I myself have an older Neal Chance. We have 4 different Chance converters that work really well but haven't bought anything from Marty in a while. There are a lot of good converter companies out there Abruzzi is another. FTI seems to have good customer service also.
