I have the 5x749 it's a zoom trick worm and it pours great. I personnaly like the micro and pyrex, go down to your local goodwill/thrift shop you should find a cheap micro there. I did the pouring pan thing maybe I didn't give it enough of a chance but the pans were crap and hard to use. I made my own presto pot which works freaking great but I found myself going back to the micro and working in 4-8 oz batches the presto pot is for larger runs. Make your own salt just grind (flour) in a coffee grinder or blender save yourself the shipping cost. The regrinds (sprue) sounds good, are you close to them as I stated shipping cost were crazy.
