Hello everyone,

I am in the process of designing my own 3D printer, and a hurdle that I cannot get over is the control hardware. I want to use a windows based tablet to run the software (Repeteir, most likely), and the problem I keep running into is that very few tablets have more than one USB port or a separate power jack.
I have seen and considered the MatterControl tablet, but $300 seems to be a bit steep for a dedicated system.
Long story short, Does anyone know of a tablet (the smaller and the cheaper, the better) that would work for this?

Thank you
