I have a Pentax LX. It's a great camera, BUT there are a couple of things to be aware of.

On the LX that requires using manual mode or adjusting the compensation for the equivalent exposure, which is not that easy, basically impossible with the camera to your eye. I think this is the one thing lacking in this otherwise excellent camera.
Another thing is that it is rather loud. I can't really quantify this, and it isn't thunderous or anything, but my little Ricoh XR-7 second body is much, much quieter (and has the exposure memory lock - in some ways it's actually nicer to use but built like a toy compared to the tank-like pro grade LX.)
Another thing that some people don't like is that the way the mirror lock up and self timer are controlled, there's no way to use both. You can't lock the mirror up and then have the self timer fire the camera. If I used the self timer that might be a limitation, but I don't so it's a non-issue for me.
The LX does have an excellent meter with off the film metering including OTF flash metering with the proper dedicated flash units, superb low light response, interchangeable finders etc. plus all shutter speeds from X (1/75) to 1/2000 are usable without batteries. It's a great camera, but (like any other camera I've ever used) not completely perfect.
