I have both. I use both. Never any problems with either, but I admit to being marginally more partial to Al for some minor favors he did me a while ago.

I use a toggle-clamp handle set I got from BuffaloArms. It fits both makers' moulds equally well. If you haven't tried this handle system, do. I started with it because arthuritis was weakening my grip. But I get better bullets with it, because the mould is closed the same force every time. The round main handle needed grip tape on it, so I don't have to hold it so tightly.
