ive been doing a bit of research etc.
it was the unit, just an earlier (2009 i think) model with upgrades.
i also found a unit on ebay with avid bb7s for 350 quid.
seems like a good deal to me.
If it fits and is in decent nick, it sounds like a good deal. I'm sure you'll get loads of fun out of it.
Those yellow Cotic's are lovely.
