I was actually looking some of those over the other day but not seriously considering buying and the model numbers are lost in my head.
I’ve dug the Leica stuff for a long time but didn’t want to pay what they ask for a DSLR. As far as the point and shoots go the ones I handled the other day were by all accounts great. That said Panasonic makes a few models that are basically the same, including the Leica lenses, they are missing a few features here and there but for a few hundred less so you might be interested in checking that out; they were probably equally as nice but without the Leica bling on the side.
Also sales dude was talking up how Leica packages copies of Photoshop Elements with their cameras instead of the cheap-o stuff you usually get. That’s pretty cool, but you’re paying for it somewhere and it might be unnecessary if you’ve already got editing software.
