I have the Bushnell Yardage Pro 500. I looked online at a lot of different places. EBAY had it for $145. Another had it for as much as $300. The best I found was for $175 at
www.pricegrabber.com
This is my first season with and have been pleased. One thing about it that I' m not sure I like is it will not range below 20yds. On the other hand, the arrow placement is almost the same for the first 20yds with my bow and set up, so it doesnt' hurt me.
Hope this helps!
