I'm sorry if I missed this, but does it need to be street legal? I do like the TW-200. I'd like to compare it with my Super Sherpa at my sandy property sometime soon. Keep in mind that if you get an older one, you can lose the electric starter, starter clutch, battery, and rely on the kicker. Bit of weight loss to be had if you want to. Plastic tank might also help. I suspect most two strokes are going to not be economical enough to make up for the weight in extra fuel, unless the newer ones are better.
