I bought mine of ebay for £150 less than retail because it was last years model. Still a brand new bike though.
Make sure you get some hybrid tyres that can handle on and off road though. They're a bit of a compromise but worth it imo.
Regualr MB tires are terrible on-road. They wear too quickly and make any journey extremely hard work. on the other hand road tyres suck off road.
I use the Schwalbe Land Cruiser:
On-road it runs on the continuous piece of rubber in the middle and off-road you just lower the tire pressure a bit and it gets traction on the knobbly bits. For road use mine are set to about 80psi and the difference between off-road tyres was night and day to me. They weren't amazing off road but i still had the PSI at 80 when i tried so it's bound to be a bit crap at such high pressure. For stuff like parks/fields/light trails though they are more than adequate.
