Thanks for all the responses, guys. And thanks especially the UncleVanya for providing the link to an earlier thread on this topic, which led to a link to the Flipbac website:
A Camera Grip for Canon S100 and Nikon V1
You know, I've never liked the looks of the Pentax grip and I was pretty serious about carving my own. And no, I didn't realize the two grips were plastic. I still think a wooden grip would work well on the LX.
But I gotta say that I really like the looks of that Flipbac. You know, being an old Canon guy, I've always felt the grip found on the A-1 and AE-1 Program to be satisfyingly adequate. The LX Grip A/B are sharper protrusions than the Canon grip. Also, grips such as those found on the Pentax Program Plus, Super Program, and Minolta X-700 fall within this same area of comfort. It doesn't need to be big, it just needs to be shaped right. And in that respect, I think the Flipbac G4 on an LX is just about perfect for that camera. As people in the link that UncleVanya provided mention, it does interfere with the self timer (see page two of UV's link for photos of the G4 on an LX). I'm one who will use a self timer on occasion, so I'm thinking that I might have to modify the grip some. See if I can cut away some of the material on the right side to give the self-timer clearance. I dunno. I might just decide to forego operation of the self-timer the way others decided to do.
If I decide to go with the G4 -- or one of my own making -- I'll post pics once I've installed it. Thanks again.
