It's on my wanted list, but a set just sold (MISB) in Spain for €65 - that's a bit too rich for my blood yet. I don't really want MISB 'cos I'm going to open and play with it, but pieces are hard to find otherwise.
I know what you mean about high prices. I paid US$35 + US$10 shipping for an out-of-box Merry Men set that was missing a few minor pieces (the sheriff's spurs and some sandals). I got lucky with the auction and the dealer, because the set was in great condition. Probably the fact it wasn't MISB led competitors to back down, or maybe even just the time of the month went in my favor.
I would consider buying it MISB for US$60, if the postage was US$10 or less. But, also, I'm really attracted to the set. I like the hunting set too, but can't bring myself to meet its now astronomical valuations ($40 and rising).
Playmobil should just re-release and bring an end to the nonsense!
