While I appreciate that .com is king and will always be imho would you rank .org over .net and even .co.uk (this site is not linked solely to the UK but woud be worldwide.
With rare exception I don't see the .Org TLD as having a significant aftermarket, especially in the realm of 2 word domains.
Here's a hard earned tip: If you are looking to speculate, and have a limited (<$10,000) budget you would do far better in the long run by buying a few decent .Infos in the aftermarket than buying all the unregistered .Infos, etc. that you can find.
The landscape is littered with people who've reg'ed 100+ domains and never sold more than 1 or 2, for which effort they've seldom recouped their investment.
It's a lot like the lottery. So many people buy tickets. Very very few ever end up with a net gain.
