I like the sign. Sometimes, you may pay a little more for something than you think it is worth because it is something you 'really " like it.
It happens to me every once in a while and I bite my lower lip and "overpay" This stuff is getting harder and harder to find.
Just my .02
I agree, sometimes its worth what you are willing to pay. If you can find another one for sale at a lower price, buy that one instead. If it is something that sells or is for sale a lot, check the market value like an appraiser would on Live Auctioneers.com completed auctions and what they are going for on Ebay's completed auctions. Don't use the one off fliers that were crazy. What it is worth is something you need to know if you are planning to flip it. If it is rare or very hard to find and this is your one chance to get it, remember that when your buying and your kids may be happy some day after you enjoy it.
Just my .01 worth. My wife reminds me regularly my opinion is only worth half of hers!
