Been there done that. I still have 2 Dillons and when they wear out they're gone. I've got 5 Tumblers. 2 RCBS, 2 Dillons and 1 Lyman 2500. My original 2 RCBS had some 5 or 6 motors quit. Called RCBS and they would send me new motors no charge. When RCBS came out with their new revised tumbler RCBS told me to send my 2 back. My cost for postage. Received 2 NEW RCBS revised tumblers at no charge. Have yet to have a problem. Midway at the moment has the RCBS tumblers on sale for around $60. Going to order 2 and replace the Dillons. Great machines. Crappy tumblers.
