Pronounceable LLLL domains in .com, worth investing in - .org probably not.
.org domains need to be very strong terms to be worth bothering with in my opinion.
Also, most people still associate .org with not-for-profits, which cuts down the potential market quite a lot.
I used to buy a few .org domains, but sales were minimal and I've been dropping most of them since. I still get .org domains for brand protection, but that's it.
I don't see any value in these, but hopefully you might get lucky.
