I know this isn't really the place to be asking this but I have been searching the web and cannot find anything so I figured I would start here.

Is anyone out there using 3D Systems 3d printers?  If so, are you happy with them?  Do they run consitently?

We have two - CPX3000 & HD3000.  Service has been great for them BUT service is in about every two weeks working on one or the other and I am just trying to see if this is the norm or if we by chance have gotten 2 duds.

Thanks for the input
