Search his store for Leica, topcon, etc. He has lots of equipment without cases, and shady looking stuff all around. I asked him for a serial number on a GPS and never got a reply. This was before I looked at his other inventory. Shady.

Looks like a legit seller to me. The downside is that everything I looked at is priced well above market.
Just an update, 5 attempts of contact about this item from 3 accounts, 2 answers from 2 accounts when I didn't ask about the serial number.
If anyone wants to do an experiment, msg him asking for details, and then msg him asking for details and serial number. Lets see who get replies.
If he is legit, this is a steal : http://www.ebay.com/itm/Leica-GPS-Model-GS14-WorldWide-Shipping-/162317224098?hash=item25cadc48a2:g:I8IAAOSwux5YJoT9
