X-S1 deals at B&H (23 January)
Interestingly, the X-S1 with the B&H Accessory Kit costs $45 LESS than if you order from them just the camera. Strange, no?
They also have some used ones at decent prices.
I am biding my time until the HS50 EXR comes out in March (or late February, hopefully), but the X-S1 is still going on strong apparently (at least until an X-S2 should be released).
