Right now I have a standard 68 Mag with nothing special done to it. I want the ReTro valve and I-frame, and maybe a lvl 10. I was thinking of maybe selling my current mag and picking up an RT/Pro (New or Used...). I can probably get $250 for it and Id just have to dish out another $200-$250. for the RT. I saw a few good deals on Ebay on Rt's 
What would be the compareable differance between Retro/I-Frame 68's vs an RT(performance wise)? Any sugguestions?
Thanks
