I need to buy a new 750 watt Mitsubishi servo and amplifier and the
list price for both is around $2k. They are available new at
substantial savings from dealers on Ebay and the Internet, usually
shipping from Asia, but the discounters are unauthorized dealers. One
of the dealers has a local office near me here in Illinois but ships
from Malaysia and he is my1st choice at the moment.

What sort of problems might be expected when buying from someone like
that or is it a totally bad idea?

I've had two different experiences with Chinese suppliers besides being
happy with the product. One was the product was a counterfeit, and only
bore the brand name to fool the buyer. The other was that the equipment
was used, and was "cleaned up" to appear new.

Honestly, most of the time I have been happy. But if you get ripped off
with a counterfeit $2K part, you really get ripped off bad.

Surprisingly, the "no-name" or "Shin-Wa-Fuh-Kew" type parts have turned
out to be mostly good deals. You'll never hear of the brand again almost
as soon as they sell to you, but it will show up with a different badge a
couple of months later, the same bolt-for-bolt, except for the glue-on
logo plate.

Do you suppose the chances of a good buying experience
might be better if the vendor has an office here in the States?

I don't know. I'd use a payment method that has some protections for the
buyer.

But $2K for one servo and drive? How big is this thing? I got a nice
set of two TECO DC servos and drives from AutomationDirect about a year
ago for a lot less than that (sized for a lathe, so your milage may
vary).

$2k is the list price for a 0.75 kW drive and amp; the price from
NexInstrument is about $1300. This is for a indexer/lathe head where
I need to be able to use the same motor for slow and relatively high
speed operations. Threading ability is important and the Mitsbishi
drive has an auto-tuning feature that should be beneficial for varying
loads:
