Used CD's as source of cash?

For quite a long time, I would purchase a new CD with every paycheck. As one would imagine, I have quite the stash. With the advent of DVD's, iTunes and satellite radio, I never listen to CD's anymore. As a result, I am considering options for the disposal of the collection. After I finish the complete transfer to iTunes, I am considering what to do with them.

Options:
1. Stick them in storage and hope some of them become collectors items.
2. Sell them on eBay. From other postings, used CD's don't seem to have enough value to make it worth the effort
3. Give the collection to charity and take a tax deduction.

Right now, I am leaning towards a combination of 1 and 3. If anyone has other options, I am all ears.
