Make sure you know the lithium ones are NOT rechargeable. They, in fact, explode.

That being said, the Canon Selphy printer packaged at Circuit is an excellent photo printer, and well worth the extra few dollars to get it. If not, HP has made a very nice one, the D7360 (there's one with a scanner for $50 more).

But I'd get the selphy, it is just so damn nice a printer for photos. Also - tiny. You could take it with you easily enough.
