Range Finder

I would like recommendations for a medium priced range finder. By medium, I am talking in the $200.00 to $300.00 range more or less. I am looking for 600 to 800 yards range, 6 power, able to range on angles. and durable in the field. Not opposed to paying less for quality, but don't see need to pay much more.

Would welcome any comments, experiences, recommendations, etc.

Many thanks...
