I have a few for my 1050, .38sup, 9mm, .45, and the unicorn .223. A couple years ago they were somewhat available, but lately they hardly come up for sale. I use the MBF collator instead of the GSI collator and I've had no problems. I think the major wear items for the 1050 version is the index wheel and the gas shock. The shock should be easy to source. The index wheel assembly would be easy to reproduce by a good machinist. For the most part, it should provide service for a long time on a manual press. I wouldn't run it on an automated press.
