I'm going to go with the R1. The choices of filament that it can run sells it for me.

Another question, does anyone know anything about using sublimation printing with 3D printed parts? I have a customer that wants a 3D printed cup for a prototype, but wants to use sub printing to make logos on it and such. I have no clue if it will work with 3D or not, since I'm still new to this.
