I paid $600 for a used USO spotter on here. It's unique, it trades a narrower FOV for extra eye relief. It's USO so it has pretty good glass and you can hammer nails with it. It's more like a 15-45x scope with no adj. Mine has the GAPmil reticle, same as two of my longer range scopes. Nobody makes anything for 'em and I wanted a spotting/LRF day/night setup so I had to get creative and make my own. Different members made different parts for me, including the awesome mount that holds it all together. The PVS14 mount was really simple and free. The Mk5 LRF I really scored on, it's good to 6 miles and was only $400 on ebay. With tripod, and minus the PVS14 and PEQ2, this setup was only ~$1150. It's not for everybody but it works like a champ for what I use it for.
I'd originally wanted a Hensoldt Spotter 60 (best there is for it's type) but a divorce ended that aspiration. The 60x Mk4 was one I looked at, it had a reticle and they also make a bunch of shit for those that they don't make for others, mounts and such. But in the end, I went with this since I wanted something rugged I could use in the field, and it's certainly that, and since I could afford it. Just gotta be patient and wait for those kinds of deals to pop up. Technically, this scope isn't a true spotter, technically it's an "observation" scope. But for it's intended use, that's fine. May make the LRF quick detach later on.
For work on the range or general viewing, the best I've used were the 60x Kowa spotters w/angled eyepieces on tall stands. It's what we used as instructors training SDM's to spot their trace and I swear to god, you could see that 5.56 round travel all the way downrange clear as day (looked just like that shit in the "Matrix" movie). No reticle, but great FOV, great glass, and if you took it a hair out of focus and used it at around half power, nothing, but nothing spotted trace to 1k+ like that thing did.
We had some rubber armored bushnells too, they were given to the students to use on the line in pairs but you couldn't spot shit with that thing. Better than nothing though.
