Hey Kim. I’ve been watching this thread ~ certainly some interesting input. But back to your original inquiry, Kim, I’d put a vote in on the Z3M. It’s not perfect, not 110% reliable, but mine is reliable enough that I don't worry about it and a heck of a fun shooter. It’s comfortable, has the large VF and yes, it’s totally manual so it's always a good learning experience. Any FSU has it’s own little idiosyncrasies and that’s part of the fun … for me anyway … learning to be comfortable operating each one in diverse situations. Linked with a good Jupiter 8 & 12 (I also enjoy the Orion 15, but they're not as economical as the J8 & 12) I can have a pretty good day out shooting.
As you can see by my sig, I like Zorkis. I like what I like and as I’m sure most here would agree, we don’t feel like we have to justify our choice of equipment to each other. That’s why we’ve all got such great and varied opinions and jump at the chance to share them! (It's also why we're all suffering from chronic GAS attacks!) The popular cry here is ~ “Get whatever trips your trigger.” FSUs can still be found at fairly good prices and if purchased cheap, you can always resell what you don’t like and try something else. The only downside to FSUs is… you can’t just own one!! And I’ve got the ball of imported Yak hair string to prove it! 😱
Good luck!
