Give that man a cigar. I do buy PropShop props and love every one of them. I have never bought any directly from them, I usually get them from a vendor here in the states. I'm a little fearful of ordering anything from overseas, but in this case I might have to. I've emailed Simon at PropShop about availability and they have the M4's and M5's in stock but not the 10-32's (thread size). They do have the kort nozzles to fit though. One of these days I will finish one of my tugs that has a 4" PropShop prop on it, they say that it is rated at 20 pounds of thrust, can't wait to see that.
