Is there anyone out there who owns or operates a Deckel Maho DMG DMF 250 Linear VMC?

We are considering the purchase of one of these units approx 2006
With there high speeds and high RPM it would seem to be good on aluminum but how do they fare adding occasional processing of carbon or stainless steel plate to the mix?

How maintenance intensive are these machines in general?

Any information would be greatly appreciated

Thanks

Chris
