You're right that spending more on a "brand" engine is no guarantee of quality. What OS was it a few years ago? Was it the OS .46 FX that was prone to peeling liners? It was one of the OSs anyway. Lots of people sent them back for warranty repair, some more than once. They all reportedly got fixed but OS never acknowledged the problem. Look at the problems with the first pumped OS 1.20 FS.

Tower engines have a good rep. I have two .46s. One has always run well. The other was unreliable until I replaced the remote needle assy. Now runs OK. I have an older GMS .47 that runs super. I've never owned a bad SuperTigre.

Right now Tower is selling the GMS .47 front-needle engine for ~$60. What a deal! If I wasn't going to get rid of all my glow stuff I'd buy one.
