Thanks for the reply.
You make a valid point about a 2-stroke. The OS 160FX is one I have had in the back of my mind. I have to admit I like the cheaper price tag.

I guess I am somewhat drawn to the idea of trying a 4-stroke as I have read that they are a little better on fuel and I like the realistic quieter sound. Are the newer 4-strokes more reliable than before or prone to tinkering?
