Just googled it and found the CVS of all places has one for a little over $100...then there's this:

Look at the Target website, they have a couple available.
Myself, being here in Melbourne, I have a portable DVD player that we take with us in the car and on vacation. Just pack the individual DVD's in a case & go. I get weather updates on the radio when hurricanes hit.

I'd peruse eBay and Amazon, then check out reviews.
