I've seen a couple of the Toon Cycles range between $20-40 boxed. A motivated buyer is the key ingredient to this sale... Here are a few examples that have sold:

If they are loose without a box, don't waist your time selling either of them. It's better to keep them as you'll appreciate them more, and profit very little if at all on ebay.
