I've never actually purchased a DLC for any game, but the side missions for Mass Effect 2 really tempt me, though.
I want to find out what happens with Liara and the Shadow Broker...
I don't have any philosophical opposition to DLC, so I bought Shadow Broker and Overlord for ME2. I think both are very good DLC and quite worth the money.
If DLC didn't exist then things like the upcoming Arrival DLC for ME2 (bridging it to ME3) would never exist. Of course DLC can (and often is) abused, but I wouldn't use this to rule out any and every DLC out there. Developers take notice of what sell and what doesn't.
EDIT: And if by chance you're a Liara fan (like myself), you'll love Lair of the Shadow Broker
