M E Cook - I wonder if the bandsaw you got is the same one I have. (Which I got from Princess Auto up this neck of the Canadian woods.) The blades are the same dimensions in any event. My experience so far is I can buy 2 different blades both 14tpi but one is almost half the price of the other. When I was buying a couple spare blades I didn't notice they had 2 versions, I ended up with the cheap ones. And they were cheap and didn't last long at all. I now only get the more expensive ones and they work well.
What ever you get have a spare on hand, nothing worse then having one last cut to go and the blade dies on you...
I can only find 14tpi blades up here btw. If you can find different pitch blades that can be useful depending on the thickness of what you're cutting. More tpi for thin stuff, less for thick in a nut shell.
