Unless you are in the NYC area and somehow are able to get them on the phone , verify, and physically go pick up the product this is ok. BUT do not do it over the internet.
I actually have delt with a company just like this one. Crappy web site, but they had a local address in NYC to pick my product up from(paid when i got there and checked product). It was a loft space in Manhattan. The item I got from them was legit, but I can see how the internet sales would have issues. The ups guy actually came while I was in the place to see if they had any pick-ups. Very disorganised they were.
Bottom line...
If you can touch/feel it. go for it.
You have faces and locations that you can verify. any problems , be ready to battle tho
