Hey All!

So, this is my second post to SRP, and I'm really satisfied with my experience; everyone has been very helpful so far! I'm also getting to the point where my college buddies I live with are making fun of me for how much I'm reading about straights...

Ok, I guess I should start off by saying that I am dangerously close to pulling the trigger on ebay (I've bid on listings already and lost them all), but I haven't seriously bid on something that I expected to win. That being said, I'm kind of glad I haven't won on anything yet because I probably could have made a big mistake.

Now, here is the listing I'm most intrigued by:
SPECIAL SALE #32- Rare! Straight Razor:72 1/2 J.A.HENCKELS SOLINGEN GERMANY | eBay

Can anyone tell me about this razor in particular, whether it is vintage, NOS, or one of the new regrinds that were recently released. I have no idea how to distinguish between them, so some clarification here would be fantastic. I guess I'm looking for some know-how on what key things I should be looking for in a listing that will indicate whether something is a good value or not.

Also, if you care to do more digging, this seller seems to be much more "professional" than others (despite only having 370 feedbacks), particularly in the picture collage setup they have there. This professionalism, the price tag, the location of the seller (Japan), and the fact that this seller has a lot of items like this one are all red flags. The positives are their feedback, and that recently people seem satisfied with the razors they're getting. Any thoughts here?

Bottom line, I think I need a Str8 razor-ebay 101 lesson. Anyone willing to take me up?

Thanks,
