Not sure I agree with you on that Olds. I had one in my Maxx a long time ago and I got over 4 gals. out of it before I snapped the conrod. It wasn't a powerhouse but had enough power to have fun with bashing. Granted, its a cheaper mill and the OS would be a better choice. But, at the time I got mine, they were selling new for like $65 shipped on Ebay and at the time that's all I could afford.
In my opinion, if you can get the OS, then that's what I would get. But, if the OS is out of reach, then the M16 wouldn't be a bad choice......
