I have the basic Magnetospeed and it does everything I want and easy to use. Only problem is you really can't test for accuracy while using it because it mounts on the barrel. If I had it to do over I would buy another. If you are working up loads it's a bit of a pain but in aint $500 either. I think I gave around $160. The ones on stand are OK I guess, never used one.
