BSUK sells individual DC2s with a cut-down lever (which is easy to remove if you prefer them without) and postage shouldn't be much more than a quid even if you buy a few at once. Otherwise the Omron SS10 is a very good alternative.
As an aside I would recommend swapping in a pair of carbon brush packs from a pair of donor FC130 motors if you'll be running this setup for a while. The stamped copper brushes won't last long at much above stock voltage/current and, if you're running a Stryfe or other semi-auto, will allow you to run the motors at 3S without issue (the sweet-spot voltage for performance with stock semi-auto motors).
