hurray! i'm glad you've come to see the light, ree. ;-)
yeah, the minarelli is so easy to work on and parts are so common. it's a great thing. i would recommend nearly anything, sine they all have the exact same v1 engine. not like tomos w/ three types. all of them are the same. same carb, same everything.
cimatti city bikes are quite nice and fairly common (they have rear tanks). but there were probably about 50 or so manufacturers who used the minarelli engine. so you can also get a really unique moped. i only know of two other bianchis (and one has a morini engine). dan has the only milani we know of (they were even rare in italy, made by a mom & pop outfit). carabelas are also nice, the only moped we know of made in mexico. some are top tank. some have rear tanks (like the asian peds). but engine parts are completely interchangeable. only four wires, so nothing complicated there.
