Another vote here for the GRD...well I have the GRDII and love it!!! Best UI (you will not want to put it down!!) and the only true compact - from the usual line up of suspects (G10, LX3/DLux4, DP1).
I don't intend to start a war here but the GRD has a unique image quality...however, the DP1 has stand-out IQ once you get over the learning curve. Many people love the LX3, but for me the images were....well 'platicky'...but again my own very subjective opinion only.
I tested the LX3, DP1 & GRDII for a week each - three of us bought one each and would keep the one we liked best....after my week it was the GRD definitely!!!...and there was some fighting let me tell you!!! But I bought the more expensive DP1 so had the loudest voice come voting time. Handling the cameras will tell you which one is for you! Funny thing is I was set on the DP1, then LX3...but experience presented me with the GRD. So don't always follow your head on these decisions...
