I know these are available on HKparts and RobertRTG (although usually OOS at the latter). I have a 20 ton shop press I am finishing building now so I don't need a work around to needing one of those. I was hoping I could find a lightly used version of these, but try as I might they seem to be unobtainium other than buying new at a minimum of $450~.
What about the homemade versions? Has anyone used any of these (for those that don't like clicking links, photos of each, in the same order are below):

Also, there is a 3D print version that at least a few people have reported works well:

(bonus points for anyone who has done these flats about whether the other jigs available from HKparts and/or RobertRTG are necessary (mag/shelf locater barrel press, etc.)
(more bonus points if anyone has similar suggestions and first hand experience with the same for Klashnikovs, but I am primarily concerned with the HK variety)
