I posted this on the G&L board, but figured I'd ask locally too.
I'm thinking of getting Bella Blue Grass Plugs from the High Country catalog.
We re-landscaped (ok, still in progress) the front yard to have less maintenance and a larger xeric area. I do still want some grass though. It seems like this is a pretty good option - 30% less water, and it says it won't need mowing.
