Thought I'd have a quick look on Autotrader only 11 for sale on there but all are 848's One 1098 on MCN but its a base model, looks like they are getting rare might be worth £50 by 2019
You get the odd one going cheap if there is no one else advertising when they go up for sale - but they are pushing 999R money now you won't loose money that's for sure
When I was looking for one (until @Robarano finally gave into my persistent pleading) I spoke to a guy called Jeff, I was put in touch with him by @Char, he's looking to sell his due to ill health. Black with gold frame, low mileage (2800ish I think), some mods, but wasn't for me as it hadn't got full history or any of the standard parts he'd taken off. Might still be for sale as he wasn't in any hurry.
