Hi Kevin:
I do not own a Prazi but have used them often enough to know they have value for the person trying not to invest in too many industrial devices.
Regarding bandmills: Converting logs to lumber with any tool requires labor. The smaller the mill, the greater the labor ( in general) It is hard to beat the lumber industry at their game. As a bandmill owner I am happiest that I bought a large tractor to go with it.
If your project uses $3000 of materials as supplied by others, are you prepared to invest $1000 in logs, $1000 of your time, and $5000 in a mill to maybe get the same stuff?

I would be glad to discuss this further and have some suggestions.
