For an inexpensive rangefinder I would go with a Newcon. I don't have one but I have not heard one bad review on them and the price is right.
I have a Bushnell Elite 1500 and was dissapointed with it so I sent it in for repair. It was returned with a note that it was within specs. Somehow now it seems to be working a lot better best I could do with it before on anythng was 600 to 800 yds now I can range to 1400 or better, go figure.
and uno mas cerveza por favor.
