Good luck, I think the prices you're basing this on are from optimistic sellers with stock and no need to sell, I can buy a new obsolete Siemens VFD for my power hacksaw for £1000, or I can go for a new model from Siemens for £100 if I shop around and can wait.
Check Zapp Automation's site to see what similar or higher spec drives and motors can be bought for new with warranty.

That's why I am asking.

Thanks for the link, cool store.
These were the closest I could find:

I couldn't find 8000 count per revolution servos, but that one is similar otherwise. These motors seem better, but the more modern drivers appear more flexible regarding I/O and probably have more modern software on the PC side. Still, a similar setup there would cost 2300 euros, which does indeed make my 1500 euros estimation a bit unreasonable. I reckon I'll put them on eBay for 800 euros, if it doesn't sell quickly I might just keep them.
