I played Puerto Rico tonight. I didn't like it nearly as much as Power Grid, which we played last week. I might have to get a copy of that, though how something with fake money and bidding can be so engaging I don't quite understand. The game design is just so elegant.

We enjoyed it but had more fun with games like Web of Power, Carcassonne, and even Age of Empires III the board game, which plays like Puerto Rico in many ways.
As to elegance, I personally like Antike. The dynamics of the wheel and the economy make it quite elegant.
Re: board gaming
My current favorite though is Tigris and Euphrates.
