I have been looking at this model. I want to make my own suppressors, and finish some lowers. I know the limitations of a 3 in 1, but for garage and hobby use, it looks like it might do everything I need. its a smithy 1324 granite. I am the type of person that would rather spend 4 months making something, than plopping down a grand and walking out the door. What would you recommend to a new owner? I would rather cry once than get something i have to replace later. CNC upgradeable is a plus.
