Just my $.02.....
I had 2 Hoyt Alphamax bows for the last 3 years. One I bought new from a dealer and put a Tru Glo 5 pin sight with micro adjust on it. I think it was about $60.00-$65.00. The other I bought used off of Archery Talk and it came to me set up with a Spot Hog 7 pin sight, I forget the model for sure. Nice sight for sure, but in my opinion not any where near the extra money compared to the True glow. I shot just as consistent groups with either bow no problem, out to 60 yards. I have since sold both bows complete and bought a new Spyder outfitted with a used True Glo micro adjust I picked up off of Ebay. Shooting great out to 60 yards at this point getting ready for a Elk hunt. Tru Glo has great customer service as well. I stripped out some threads on the used sight, and while taking it apart lost a spring and a ball bearing in the micro adjust ratchet system. I called to order parts, they shipped me the parts I needed and extra's to replace the other side at zero cost to me. Again, just my $.02 to save you a little $.
