your experience with mod or upgrade companies.....

i called c/j and talked with jeff, found out that cj now does upgrades for some of their equipment. my pv12 would be about 900.00 four just 5 caps. that seems a little high for just that amount of work. what other compy that you know of is doing this, i know a while back i heard about different ones, but you dont hear to much now. there was a group of indian guys i talked with a while back that seem to do a lot more for at lot less, but i forgot the name of them.. please give me your input, as always is appreciated.......
