That's embarrassing, I didn't notice that you had owned an X100... Sorry for skimming your post :/Hmm, I see.
I was honestly satisfied with my Fuji, but thought I would get a DSLR which could do both photo and video for my video production.
But now that I am getting a pro camcorder, I regret selling the x100. I guess I should just go rebuy that. Since Leica is so pricey.
Again, I'd wait for someone better qualified to chime in as I'm by no means an expert in the field. To me the X100 just seems like the goto digital rangefinder south of 5k.
If you're willing to go for Sony they have the RX1 which is full frame and has a sharp 35mm lens, but lacks a viewfinder. Its MSRP is 2799, but I know it has had a lot of deals and checking Amazon I found several refurbished priced at ~1600. The A7 is ~1300 now if you don't mind the looks. It ticks over 2k with the 35mm Zeiss lens though, kit with 28-70mm is 1700.
Edit: I should maybe have asked this earlier, but what type of photography do you want to do? I'm guessing you want a good looking and feeling camera considering you wanted a Leica.
