The Stinger 3G is an amazing bow, at any price. Don't think that just because it's the cheapest bow PSE makes, that you are giving anything up. If I were you, I wouldn't blink for a second when considering the Stinger 3G. If I were to pick on the bow at all, it would be the factory strings. I had to readjust my Dloop and peep sight a lot while the strings were settling in. It took my strings over 1000 shots to fully settle, but my peep and Dloop haven't budged in thousands of shots. If I could do it again, I should have replaced the factory strings sooner, with a custom set from 60X, to save the headache of the constant peep alignment. You can usually get a set of custom strings from 60X for right around $60-$65, and they are worth every penny. With a well made set of custom strings, you install them, shoot them 50-100 times (one shooting session worth for me), and then install your peep sight, and tune your bow. Then you can forget about your strings and peep sight, they won't budge.
P.S. If you don't mind the rubber tubing aligned peep sight, you can shoot the Stinger 3G right out of the box, with no problems. I did for a while, and had absolutely no problems. I ended up breaking the rubber tubing a couple of times, then just pulled it off, just to see how stable the peep sight would be without it. I had to keep readjusting my peep sight rotation, by separating single strands on each side of the string, and moving the single strands to the other bundle of threads. A little headache to do, but it was worth it. I love my Stinger 3G, and don't have a single regret buying it. The factory strings are extremely durable when they finally settle, and I lost my shot count at over 5,000 shots.
You won't find anyone say anything bad about the Stinger 3G, other than the factory strings. That says a lot about a bow and what to expect. Don't let the factory strings keep you from buying the bow, as you can always shoot it with the rubber tubing aligned peep sight until the strings settle, and then for $5 you can get a nice aluminum peep sight with no rubber tubing. Or do what I should have did, and put a set of custom strings on it, and forget about it. If you think about it, a string is an extremely important part of a bow, and for such a cheap price, why not have the best? I would put a $50-$65 set of 60X or Twisted Archer custom strings on a $1000 PSE or a $1300 Hoyt, and you can have that same top quality custom string on a Stinger 3G. A $299 bare bow price, plus $50-65 for a custom string if you want, and you will have a bow that you can shoot until your arms fall off.
