Commander is a real killer at the moment. I think I've spent more money collecting cards for EDH these past few years than I ever have on standard. I count myself a little lucky, I picked up a Polluted Delta back when they were only $30. Now I'm wishing I'd some the same when Imperial Recruiter was only eighty.
Have you seen the new sealed multiplayer set, Conspiracy? It's supposed to be a lot of fun to draft, and there really aren't any money cards. I picked up all the singles I wanted from the set for under ten bucks, including a badass alternate art Rout featuring Elesh Norn.
My FLGS is also trying to lure me back into the fold by saying that my old cards will be usable in Commander. Thus far, I've been able to resist looking up what it is.
Which does remind me that I've got a suitcase with thousands of old cards, just waiting to be resorted.
