Mercenaries 2 for $2 is a great deal, I remember the game getting a pretty mediocre reception but it's still really fun. Very similar to Just Cause 2 but not quite on the same level.
Also I wish there was someplace that sold Mercenaries 1 digitally. Is there?
I think you just provided the extra push I needed to get the game, though I wonder why it got mediocre reviews. And I've never seen Mercenaries 1 anywhere... according to Wikipedia, it was never released for PC. I remember how I wanted to play it when it first came out for the original Xbox, but I couldn't afford it since I was in college.
