I just bought a Xpan with 45mm a few months ago as well. Saw and held one for the first time at a out of town camera shop, then drove home and thought about the price of it too. After a week or so of feeling itchy about it, I though why the ^%&* not and now you know where my tax return went this year.
It's been a wonderful camera to shoot with. Its been taking a bit getting use to using a rangefinder instead of a SLR and I wish the lens were a bit faster, but boy looking at the first negatives out of the wash and it was all worth it.
I sill am trying to find a negative carrier to accommodate the the double wide negative, and I have found a couple and will order one when I figure out whats compatible with my enlargers. Enjoy!
