Found this Dewalt Flexvolt 2.5 gallon battery powered compressor on sale for $199 at Fleetfarm (linky) [fleetfarm.com]
plus $19.95 shipping. Total is $218.95 with no additional tax (at least for CA).
I'd been looking for a smaller, more portable compressor vs wheeling my 10 gallon around. I found this and figured I could keep using my existing pneumatic nailers instead of replacing them with expensive battery powered ones (although I'd love to). This compressor costs $299 at Home Depot and most other online retailers.
