I have a Chippie with the original drive. It's a bit worn but having a DRO means it can still turn out accurate work. It is inherently noisy due to the toothed belts in the drivetrain. I run mine from a VFD to convert single to three phase. I am on 60-Hz power but I mostly leave the VFD frequency at 50 Hz so the speeds correspond to the nameplate. Sometimes I lower the frequency when winding springs.
I have a Monarch 10EE and it takes the same D1-3 spindle tooling as the Chippie. That is a great feature for me. I usually keep a 3-jaw chuck on the Chippie and use collets on the 10EE. I use the Chippie for rougher work, work that won't fit the biggest collet (1-3/8"), and work that needs the Chippie's clutch, like winding springs and running threads to a shoulder.
A 575-V motor is a pain in the US. I do run an Aciera F5 mill with 575-V motors. For that I built an open delta 240-575V 3-phase transformer system. It was nothing that money and time couldn't fix.
As for value, it all depends on condition. It's not for sale, but I'd be happy to get $3500 for my Chippie including the VFD, DRO, an Aloris toolpost clone with one tool block, a faceplate, and perhaps an old chuck. I would not be surprised if the best I could do on a quick sale was $2500.
