I've noticed that you can get surplus NEMA-23's cheaper than the NEMA-17's sometimes. Probably because the surplus dealers KNOW that the 17's are wanted by the reprap builders.
If you can modifiy your design to work with the 23's you could save money. The 'short 23's might not weigh much more than the 'extended 17's.
(I just bought 5 surplus NEMA-23 motors rated at 2.7v 1.8A 1.5ohm for $5 each at a hamfest.)
