Spaz,
What are you using your bow for mostly, or singularly? Do you shoot 3D and hunt? Or just hunt? If you just hunt do you have a fixed yardage you are more than likely to shoot from? And, how much do you want to spend?
I had a Sureloc Sportsmans Special on my last "hunting bow" that was a single sliding pin. I absolutely loved it. Couple that with the Archer's Advantage software and you have a winner. They are very expensive though, and unless you know how far you are shooting from it may not be the best for hunting. They do make a sliding 3 pin sight which would be better for hunting. HHA also seems to make some good sights that are similar to the Sureloc.
If you want a 5 pin more traditional sight I have heard great things about the Spot Hogg sights, and G5 makes a very nice one also. I would get on archerytalk.com and check out their classifieds. If you are patient you will be able to find something there for a great price. Make sure you check their feedback before you buy it though. If you get there and register send me a friends invite, my name there is SaltLakeArcher
