Hello OP, my nickname is Trash, please throw it my way if you're so inclined.
Now, seriously, if you are going to sell it, let us here know.
I own two, three of my buddies have one as well. And, there's probably another buddy, who wouldn't mind upgrading to it.
In all honesty, I really haven't needed to tinker with them much at all. Yes, there is some tweaking/adjusting of the indexing pawls, and a little on the primer feed, but that's normal. I bought my first one used, had to replace a couple of parts, but no real tinkering involved. The second one was new, and again some adjustments, but no real tinkering.
Are they perfect, no, but they are pretty good presses.
