I've built seven mb's now and w/o a doubt, the BMP friction drives with 4 strokes are my faves. Thing is, you're talking comparable money in a "better" mb and a scooter or moped. But, since I really enjoy riding and occaisionally pedaling my mount, the mb fits the bill. I'm already pricing out build #8. I've learned my lesson on the cheap junk. You guys were right, as usual. One big thing is to have a donor bike that fits you. Most important on long rides. Since going to better tire tubes I've not had any more flats. MB's aren't everyone's thing and it's a shame to put a grand+ into something you lose interest in quickly. But if you enjoy the hobby, do yourself a favor and spend more and get LOTS more. The Worksman's salesman told me they sell alot to mb'ers. They're getting ready to sell to another! I can't wait!
