I've had a few, even a couple were new. They are fun as hell to ride, however they are cheap Chinese crap and will fall apart unless you maintain them religiously and that may not be enough. I'd say that for a kid one would be OK to learn on if it can be bought cheap enough. Personally I'd get a doodlebug or motovox if I had to go Chinese, you can more easily modify one and or upgrade the powerplant without a huge undertaking. All that being said the one you pictured is not worth walking across the road to get for $100, it has likely lived all it will looking like that.
