catt--You are right as far as I know, however someone might feel the need to correct us with their obviously superior knowlege.

The reliability of the 4 stroke is greater due to the things you mention. I think we need to try and help eache other out with as much information as possible so that our friends here can make the best decision regarding their new purchases without, as JoeM puts it, flaming someone. I thank you for your input in this thread and hope Don can use it for his benefit. After all, thats what we are here for.
