Why not use "mind-your-elders.com"? It's available. Or something like it. don't buy from the others unless you really have to.
PS: Domain squatters is such a harsh word -- some of us buy domains for future development and may leave a .com/.net/.org pointed at something until we get around to developing them. I know it is a frustrating thing as I've been on both sides of this discussion. Domains are property...and the easy land rush has come and gone. Now it's all about drops, the after-market, creativity or trend catching.
Also, as for buying directly from an owner, you never know until you ask what someone will sell it for. I've seen some pretty good domains go for very low prices (xxx range).
