I have an aftermarket frame, probably not the right one, but so far it has been a chalange. I wish my old frame was still good, or just bought a used one that was not hammered. I had big plans, at this point I just want to make things work, I hope. Just my 2 cents, I may have just picked the wrong frame. For the money, I would be way ahead of the game if I used a stock frame. I'm learning as I go.
