I bought one of those new Craftsman 4 stroke engines that you don't have to mix gas & oil and has an oil reservoir. Easy starting engine and runs and sounds great. I'm wanting to get some time on it so I can get another, (so wife won't kill me) and use it on a plane. The weedeater only cost me 180.00 from Sears. I'll be interested to know what you go with and how it works. Best of luck and let us know.
