I did the same thing when I first got on the forum (about a week ago). It seems that the differences between scooters and mopeds are a bit of a sore spot around here.
I've spent a little more time than I am willing to admit over the past couple weeks researching scooters and mopeds. From everything I have read Roketa is not the way you would want to go for worry free, high quality.
Like VN said above you could find a good tomos for that price or you could find a very good used scooter from a more reputable company. Either way you would get something that would be a lot more reliable.
Cheers
