Alright, thanks everyone! I took into account everyone's advice and I ended up choosing the Summa D75, for the following reasons:
1. Constantly hear about the high quality of these machines.
2. It has "MicroSprocket media transport rollers" which, isn't sprocketed rollers, but nonetheless, might add a little bit extra for tracking
3. Drag knife with tangential emulation mode.
Hopefully I made the right choice! I'll post some examples of my work created once I get a bit of experience under my belt.
