I love me some good House. Wolfgang Gartner is probably my favorite house artist, but Deadmau5, Danger, Justice, and The Bloody Beetroots are all good/great.
Oh, and you totally don't have to buy compilation CDs for a lot of house music (though you can). Most of Gartner's stuff is EPs or Singles, but all the other artists I mentioned release full albums or EPs.
That said, albums:
Justice - Cross
Deadmau5 - 4x4=12
The Bloody Beetroots - Romborama
