That said, although the DY was one of the more common JEMs, it was phased out nearly 20 years ago and good examples at cheap prices will become more and more scarce. eBay allows the market to find its own level and that might just be at prices a lot more today than they were 10 years ago.
I've talked with Sebastian about the DY in particular and we don't agree on this one. There are a lot of factors in play that make the DY not comparable to either of the Universes that he listed. Among them:
1. It has been out of production for a very long time.
2. A number of features of the guitar (neon paint, maple board, fade-prone pickups) don't tend to age well and make good examples of the guitar even harder to come by.
3. There was a serious recession in the US for a few years, where the largest percentage of the guitars are.
4. Most of the real bargains were snapped up by collectors who aren't likely to put the guitars back into circulation.
5. Even the people who sold at bargain prices probably turned a profit in many cases. Why shouldn't we assume that the same thing wouldn't happen with the guitars that were all over eBay the last three years?
I know almost or certain that I could make some serious profit if decided to sell some guitars today (GMC, LNG, SK, my Voyagers). But there are other guitars where I could at best break even and some of those are equally as difficult to find. A few I'd almost certainly lose money. The point is that the market is specific to the guitar; you can't make broad generalizations.
