On my RIX SA3, the easy 3rd stage piston kit includes the assembled piston and insertion tool and costs over $700. Since I had actually broken a piston, I had to buy a new one. But I discovered if I bought the piston and rings separately and assembled them myself, it cost half as much. When repairs get into the $700 range, and a brand new Coltri is $2995, you begin wondering if you should scrap the old and buy a new one. It was a close call but for approx. $350 in parts, I got the RIX back up to running as good as new... So it was worth it. The thing is, a lot of my repairs have been a guess as to whether the thing I was repairing is what was causing whatever problem I was chasing. I enjoy figuring stuff out. But, I have to say I'm not so sure I have saved much money buying used and fixing up! (A brand new Coltri MCH-6 or MAxAir 35 could be paid off in a year at $250 a month).

This has been a fun project to work on so I’m not throwing in the towel however I’ve defiantly reached the point of diminished return.
