Should I sell my iPad 3?

I decided on a whim to post my iPad 3rd gen to ebay for 350 a few days ago.
It currently has one bid, with a few watchers.

But, Im beginning to wonder if I should pull the auction and if this was a good idea at all. Im going overseas in a few weeks and was wanting to grab a higher capacity iPad to take with me, but now im thinking I may be better off just keeping the one I have. Any thoughts? Should I keep the auction up and get, say a 32gb iPad Mini, or pull it and stick with the 16gb 3rd gen?
