The Sigma DP Merrill cameras are not well loved, but worthy of consideration; see Pixel for Pixel, *Nothing* Beats a Sigma DP Merrill. The Sigma dp Quattro cameras are a follow-on product that offer high performance in a compact package also.
Currently, the Sigma dp Quattro cameras are heavily discounted, by $300 (30% off). The Sigma dp2 Merrill is also $300 off.
See my in-depth review of the Sigma dp Merrill and dp Quattro compact cameras: they may be the right choice for some users. I consider the dp Merrill line to be a 'cult' classic camera worth having: very compact and light, outstanding lenses, unique imaging style.
There are two reasons for such deep discounts: new products coming out, or slow sales. I deem the discounts almost certainly the latter: slow sales. If Nikon and Canon cannot sell APS-C for months now even at deep discounts, why should Sigma be any different?

I bought a DP2 Merrill shortly after it came out, knowing full well about all its quirks. I've always been amazed at the image quality, particularly now viewed on my new 5K iMac. Just stunning!
DIGLLOYD: the 4800 X 3200 images from the 14-megapixel DP Merrill line fit the 5120 X 2880 iMac 5K display well enough—a stunning view that may knock your socks off. (If only Apple would make a 3:2 aspect ratio display of 5120 X 3400 or so, or better yet, 6000 X 4000—that would be much more friendly to the common 3:2 aspect ratio of most cameras).
As an aside, it turns out that the Lupine transport case from the Lupine Betty lighting system is a handy thing for small camera systems. Zippered and with a carrying handle and small pouch (not shown below), it fits the bill nicely.
