Wow, I've looked and looked, but still I'm riding the fence. I don't feel better about any one engine than another. I'm really wanting to stay away from ys because I'm not familiar with them at all in their pressurizing and all. I did have a saito 72 that ran alright so the saito 100 seems like a good choice because it weighs in around 20 oz. with the muffler while the OS 91 FX is 24.4 with muffler.

I don't want to start on a brand that I haven't run before so I guess it's between the Saito, the OS 91 and the 108.

Any other ideas?
