Not to put too fine a point on it, but I "roll my own". By that I mean that I bent the hammers down on two of my very inexpensive, German made SAA clones. It isn't all that hard to do, but there are several things that you have to keep in mind while doing this. I won’t bore you with the details here, but if you are interested, P.M. me and/or E-Mail me and I can explain how to avoid some of the mistakes that I made.
