I have a MEC Grabber that I load 12 ga target loads with and a 600jr that I load 10 ga hunting loads with. The MEC loaders will give you the most bang for the buck.
As for case life I have some 10 ga Federal hulls that I have reloaded 10 times. The best 12 ga hulls out there are the Win AA, again some I get 10 or more loadings out of them. Case life depends on the type of loads you are shooting. If you are shooting target loads with lower pressures and faster burning powders you will get better hull life and vise-versa with slower burning powders and magnum loads.
I have owned my MEC reloaders for a little over 20 years now and they are still going strong, I don't think the Lee will last.
