Don't use auto appraisal tools. They are incredibly inaccurate for the majority of domains, and cannot compare to a humans understanding of how all the data used to give you an appraisal comes together and its true market value. The problem is your domain is not in a tld that makes sense for the niche it operates in. FlashDrive.com/net and english language cctlds are likely going to garner sales in the x,xxx+ range.
.ORG is more targetted to foundations/charities/NFPs
Flash.org great
Drive.org great
FlashDrive.org niche is more focused to a commercial marketplace.
Still mid XXX+ would be a nice bit of profit if you paid reg-fee to low xxx for the name. I'd email any companies using a lesser extension or using a longtail .com like flashdrivestore etc and quote them $1k and accept any counter-offers in the mid xxx range. If you really want this to sell you gotta do the groundwork and not sit and wait like the guy with usbflashdrive.org.
