Gudcraft blades?

[Scott]

These look like they may work well with my pma mills, anyone try them or know anything about them?  I've found 3 different types all the same price.  I'm willing to give them a try if I decide which ones.

I was going to order the ones on Ebay(link below) until I found the others.

I just noticed on the Ebay blades....."Turbine diameter - 1.12 meters" 

That's pretty darn small
