Does anyone here own one of these Hertz spindles from Turkey?

I have been having trouble finding an affordable used Colombo that I am comfortable buying so I am looking at some of the alternatives and these Hertz 2.2kw 18,000 rpm ER25 spindles keep popping up in my searches:

It seems like they would be a step up from the Chinese spindles sellers on eBay but I have no data to back that up...

If anyone here owns one or knows about them, please can you tell me how they perform and if they are worth buying over the slightly cheaper Chinese variety?
