captain, I don't know. I've been looking around for a 600-18, but it's kind of pricey. At $220 it's even more pricey. Although I had trouble with my Neu, it's likely going to turn out ok in the end and I think that the Neu will be a better motor. I got the 1512 1.5Y and I paid less for it than the price of either of the Kontronik motors.

Still, curiosity might be the better of me.
