You guys are making me feel like I wasted my money on Dillon polishers. The original small polisher had the little open frame motor. When it died they made me an offer I couldn't refuse to upgrade it to the same motor they use on the CV-750. The power is astounding compared to the original motor. It will probably last as long as I do. I also have a CV-2000 that I bought used. The motor is a little noisy on it but it is so old the bowl and lid are not the same material that they've been using for a long time. The lid appears to be vacuum formed ABS plastic. No idea how old it is but I can put a LOT of brass in it and it doesn't bog down.
The smaller Dillon has always been whisper quiet unless it has too much brass and not enough media.
