http://m.ebay.co.uk/itm/321399202303 Same motor you linked but a little cheaper.
If you're going to go with one of these motors see if you can find the Toro X8ST 2250kv. It's a little longer at 74mm which means it'll have more torque (for lower temps) and it's also a 1Y wind. Wye or "Y" winds are more efficient than the Delta or "D" winds like the 2150kv 2D wind you linked. I couldn't find any compatibility issues with your esc.
