I had one up until about two weeks ago. Fantastic fun, even with my fat arse on it. I only got rid as I haven't got space for two bikes and wanted something more practical for longer runs, but I do miss it.
They hold their money well so are expensive for what they are but you tend to get your money back if you sell them on.
I've got a upgraded rear shock, a fuel controller and some other bits that I removed from mine before I sold it that I really need to get around to sticking on eBay.
