Cherokee1,
No experience with the JM, but I have a Performance Center 625-7 5" that has the best trigger of any revolver I own. It is a real pleasure to shoot. I also have a standard 625-8 4" and two 25-2's (6" & 6.5").
You are doing it right - save up for it. Get a part time job, sell scrap metal, fix the car yourself instead of paying someone else. Do what you gotta do but don't go into debt to buy toys. They are expensive enough without paying 18% interest on them!
