We been using this Roland MDX-650 and it has performed as advertised with no issues whatsoever. The software Modela Player 4 is very easy to use..anyone can learn it in a hour. Machine requires air and 110V.

Does anyone know where to find a good dust/chip vacuum?

Thanks

BTW..this is not a wood router...we've been doing plastic and it is designed for aluminum and brass also.
