Stan I still have four MEC 9000HN's, hydraulic machines, which I used for several years. With them you don 't need to bolt them to the bench. They will sit there just fine as you load on them. I bought a Spolar Gold with four gauge die sets about two years ago. My second Spolar Gold machine. First was a 12 gauge, which is on permanent loan to my oldest son. I had stopped loading 12 much and was happy to see him use it and shoot more. Instead of getting it back, and sharing long distance, I just waited until a nice one came along.
If you buy a good machine like a MEC or PW 800 or Spolar and take good care of it, you wont loose money when you sell it. Age is nothing to a well maintained machine. And when you get them properly adjusted you can load buckets of shells without much effort. Heck I still have a few 600JR, old style around and will load a few shells on them if needed. Speed is nice but a 600Jr. takes me back to my early days.
