Luxman Knockoffs or Counterfeits?

Not sure they're hard to find used in the US there are 146 listings for used Luxman gear on US Audiomart.

I should have been more specific: I have been looking for the M-700u and the L-590AXII. I did see 1 of each on usaudiomart, but no success with either listing.

I'm wondering though, how safe it would be buying from an ebay seller from Japan.

I suggest only purchasing from the USA. Keep looking and waiting. As mentioned above you need a step-down transformer which isn't the end of the world but I don't recommend it.

If you buy a Luxman off of an eBay seller and for whatever reason your not satisfied, file a report with eBay and they will put a hold on the eBay sellers account and rule in your favor.

I sold a broken tool recently for parts, pictures of it broken and sure enough the guy said I misrepresented the item, eBay put a hold on the funds, 15 bucks and 5 shipping. The buyer has gotten it for free from me because according to him I would have to send him a pre paid shipping return label. Buyer knew what he was doing and got the item for free.  I would image a lot of gear sold in Japan and shipped here is fully refunded and the buyer keeps the goods. It would have to be damaged or seriously misrepresented for myself to keep something for free. 

Is there any reason using a step-down transformer would degrade sound quality?
