My LBS (http://thebikeworx.co.uk/ in Dundee) had an Onza Blade in stock if you want new - it was in their sale with 100 off the RRP can't remember the exact price but think it was around 399 or 299, will be a 2009 model I think.
I'm trying not to look at the new ones as they're a bit over budget. Especially when my cars got an MOT looming (and I have my eye on a frame of Robmacs :roll: )
