We buy and broach pulleys from SDP-SI. It is a lot easier only having to source pulleys and not pinions. We previously had issues reliably sourcing pinions. It would be nice to be able to buy hex broached pulleys, but I don't know of a source for that yet.
MXL may be close in pitch size to GT2, but GT2 has significantly higher power ratings than MXL. I don't remember the number (you can find them in the Gates manual if you want), but it is close to an order of magnitude of difference. I doubt that MXL would handle the motor torques, but you should check the numbers yourself.
