Don’t want to discourage you from investing in a professional machine but…considering how fast technology is changing, do you think you can pay back your machine with the net margins (not your gross sales) it will bring you in, say, max 3 years ?
I say 3 years because most likely you’ll want to buy a new machine with new technology within that time span, if not before.
An alternative is to build oneself a machine, maybe starting with a base like a Titan1, and make it evolve as technology changes.
I think.
