I bought a used Grand two years ago. I had 3 MEC reloaders before that, 650, Grabber and a 9000G. The MEC's worked fine, produced decent shells, but the Grand is a significant step up in quality and smoothness of operation. I was missing a few accessories and parts when I bought the reloader. I called RCBS and explained that I bought it used and needed parts and was willing to pay for them. RCBS sent the new parts, no charge and free shipping. My powder drops are very consistent. The crimp stages are similar to MEC: pre-crimp, crimp, and final crimp. I reload Federal GM, STS, and AA without problems. I like the feature of it not dropping powder or shot if there is not a hull present at that stage. I think that their manual could be more descriptive in explaining the crimp adjustment for each stage. You have to watch the primer drop, but if you put 10 primers in the primer drop tube before starting like ABH said, no problem.
