I had bought an RCBS Partner Press kit some years ago - Cabela's.ca sale(?) - was $112.99 after taxes and mailed to me. I had an idea to set up a second press for de-priming - never did that. I passed that kit along to a local younger guy who is wanting to get started in reloading - he unpacked it from box - tells me there is no capacity to insert fresh primers - so need a separate priming tool? Also, need the correct shell holder for the press for the cartridge that you intend to load - they usually come in Lee die sets - not so with most other brands. As we discovered a few days ago, not going to get much done without a shell holder for the press, for that cartridge. And is different shell holder than used on the Lee Case gauge trim system, and different again from the various Lee Hand Held Priming tools, and might be a still different shell holder depending if you choose to use a lathe type case trimmer - those also need the correct pilot stud for that cartridge. So can get to be sort of a "horde" of "bits and pieces", if you reload for more than say, 5 cartridges ...
I started reloading with Lee Loader tool, then got a "JR (?)" single leverage RCBS press - I now use an RCBS compound leverage Rock Chucker - my impression was that the Partner Press was way lighter built then those others - although, I suspect is adequate for most hand reloading operations.
