I got a huge tax return a couple of years ago and with that money I jumped on a Leica M8 on eBay. I had buyer's remorse for months because it was a huge expense but I have also not regretted it. It is my carry-everywhere camera and my photography has improved a lot since I got it (if that makes sense).Oh well...anyway, I'm still struggling with what I have paid for the X Pro. I do love the camera but it was a huge expense for me. I haven't regretted it yet but I have thought from time to time that perhaps for me (and my complete lack of photographic skills) the cost wasn't justifiable.
The last part of this comment is where I'm at. I think everyone has their own standards, both financial and what they'd be willing to pay for something regardless of financial means. I suppose if I was willing to shift enough stuff around and buy nothing else and not travel for a while, I theoretically COULD buy a Leica. I know people with less means than I'm fortunate enough to have own them and are devoted to them. For me, though, I would just simply never think of spending that much on a camera. The Fuji was a REAL stretch for me - more than I'd ever spent on a camera before. But, lets face it, $1700 isn't that overwhelmingly much more than the $1200 I paid for the X100 or the nearly $1000 I've paid for a couple others. And I've certainly spent $600 for a lens before, so the Fuji lenses aren't all that costly. And I tend to sell stuff before it loses all that much value, so I rarely have all that much sunk into camera gear at any one time. Maybe all totalled up almost as much as one Leica body or one expensive Leica lens. Or a top line pro-DSLR and a lens or maybe two. But I have a lot more gear than that and I value the variety of shooting experiences more than I would having just one of the creme de la creme (or however the French would spell that!)Here in the US there is such a widening gap between what used to be middle class and for lack of a better term upper class it's so hard for me to understand how someone can afford lenses that cost $3000 or $4000. However, I certainly don't begrudge people owning them. I've never used an M9 (and I'm sure never will) but even if I could afford it, I'm just not sure I could justify spending that kind of money on a camera and lens. I guess a basic camera/50mm combo is more than $8000 US.
