I bought a Rockchuker as my 1st press back in 1979 and have had zero regrets. When I decided to get another full set of loading tools in the mid 1990's, just for the heck of it, I got another Rockchucker.
One note I might make here is that RCBS changed the dimensions of the Rockchuker somewhere along the way so that the dimension from the shell holder to the die bottom is different. I don't recall the exact difference, but it was something like .100 inches. I fixed that by making a washer on the lathe to offset the difference. Another better way would be to turn the top off the large nut in the taller press so they match. If you aren't swapping does between the two presses, it wouldn't matter.
