You'd also have to really want the LP Junior Tribute DC bass to pay some of the prices on EBAY. I don't know what's going on with that. I rarely keep up with EBAY.
All of those listings are from Japanese sellers. Most or all of them don't actually own the basses and don't have them in their possession. If you buy one, the eBay seller will buy it at a retailer for somewhat less and ship it to you.
No one in most of the world will buy one at those prices, but these sellers have also been doing it with used gear for several years now, and occasionally a decent deal pops up. A couple of years ago, Ilan bought a used bass from a Japanese seller that was listed by several other sellers. Even after Ilan received it, at least one other seller continued to list it.
