I just took delivery today on a 900 CRF today, from Euro-Optics. I paid $436 via the auction route on eBay. They provided prompt delivery. I took it out (had to) and tested its ability under my real-world conditions and was very pleased. There wasn't a place I could point it under 800 yards or so that I couldn't get a measurement. A few measurements came back over 900 yards.
I had no trouble getting returns off the brown grass, dirt or sage. I am delighted with the choice. I'd bought a Bushnell Scout 1000 last year and it pooped out after about 250 yards. Sold it cheap.
I like-a Leica!
