Well, I did it. Finally pulled the trigger on a Master Caster. I was getting tired of hunching over my Lee furnace.
Anyway, with shipping, it will set me back a little more than $1K. The folks at Magma told me it would be 3 - 5 weeks before it would ship. A couple of good things: Magma won't charge you until the unit ships, and the MC purchase comes supplied with one mold block of your choice.
Fingers crossed that it will have been a good purchase!
