You and I are about the same age, actually I'm a little younger but I imagine you're better looking so it all works out.
If you get one you'll need some extra stuff. A biggie is drop down plates, one for your bench pin and one for your mini ball (that's actually a shelf). Oh yeah, you'll want a GRS mini engraving ball.
The drop down plates are needed because without lowering your work you'd have to raise your chair ridiculously high to get it in focus.
The mini ball is needed because with it you can easily rotate your work and slide the ball into the field of view in the same motion. If you try to use your benchmate you'll constantly be forced to move your scope whenever you move the work. The shelf provides a nice place to keep your stone tray and burs too.
I'll attach a couple of pics. Note that I add lightning on either side as well as the led ring light on the scope. That really helps.
Also note that I like a snack. The crackers are Big Wheat Thins. I like the big ones because they're easier for my old eyes to see.
