There’s not a lot of choice other than a break back style Norbar if you want to get up towards 1000 nm. If you can cope with under 800 or 700 there are clicker style options.
Norbars are always cheap on ebay used and even when factoring in calibration (and you will have to get it calibrated) still a big saving. I’ve bought 3 or 4 and not had one yet I would say had seen heavy daily use.
