I have a Spott Hogg-Hunter and love it. It is really durable and in the 3 years of using it nothing has broke or malfunctioned. I hunt in the cold Michigan winters and always had trouble with the fiber optics breaking. The Spott-Hogg sights are all very good, however, the cheapest one is around $90. Check out Ebay you may be able to find one that is less expensive. I have also been told by several of the archery shop guys that Sur-Loc sights are really nice. Not sure how much those are but I believe they are also a bit pricey.
