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
