Mouth breathers need not apply.
In two thousand hours, two different machines, I have found countless things that no one was looking for. I have sheared bolts, ruined pockets and teeth. I have had situations where I thought afterward, "I can't believe I did not trash the belt." And yet, I have never had a belt failure. They are pretty bullet proof. I saved previous worn belts as a back-up. If I were you, I would buy the real deal for a back-up. Then use it when you replace the gear set and keep your old belt as a back-up.
