Pick a place that has little or no up-front cost to you. In our area, New England, there's a publication called the "Want-Ads". One can pplace an advertisement for free, and only pays a small percentage of the sale price to the publication when the item is sold. Around here, these things become book-like, and appear new on the stands weekly or bi-weekly (I think). They have an enormous reading audience, so you may find a buyer that way.
