Why mention the snare and all of its "amenities" if it's not included? Shady.
I agree with Mark, and these did flood the American market back in the day. However, that was 50+ years ago, and although there are still plenty of them around, you see more vintage USA made stuff than vintage MIJ available nowadays, at least in my opinion. These were certainly not of the build quality their USA counterparts have, but that doesn't mean they are bad or even inferior drums. I am an MIJ aficionado, and as long as the shell is in good shape and you choose the right heads and tune well, they can sound very good, and it's a much less expensive way to get a vintage kit from that era, without paying for a Gretsch Round Badge or Rogers Holiday. I don't think MIJ kits should be given away for pennies on the dollar, but because of all the points Mark made, they should be priced well below their USA made competitors. And, like anything else, condition plays a major role in "market value", and ultimately, selling price.
Having said that, without the snare, I think $250 is the most I would hope to get out of it if I were the seller. It might be clean and it looks like it comes with the original cymbal arm, but there is probably wrap fading and and interior issues, like re-rings lifting slightly is fairly common on these kits, which can only be found during an in-person, hands on inspection. Plus, the wrap is pretty common, not very rare. Even if this is in 100% pristine condition, the seller is asking more than twice what I would expect to pay, especially without the snare.
