Where to buy Roland MPX-60 spare parts?

United States

Hi everyone, I would like to try my hand at the engraving business, but on a small scale. I have been in the market for an engraver, but it looks like spare parts are difficult to find for any MPX model below the MPX-60. I'd like to buy the MPX-60 because of the lower average cost, but I know it wouldn't be wise unless there are spare parts supplier somewhere.

Any help would be very much appreciated!

Regards,
Ed
