I think the K-S1 is the follow up to the K-01 concept, personally. I love how small mine is (I think it's the smallest digital Pentax other than the K-01, ever?), especially with a small prime attached to it. But it also has that wonderful optical viewfinder, the same as the K-3 (and all cameras that followed). What it does not have (nor does any camera other than your K-01) is the live view where you don't get that "double mirror slap". Again, the K-01 is the only Pentax that does not have that because it is mirrorless. Someone can correct me if I'm wrong...
There's a nice white K-S1 in our forum's marketplace right now for a couple hundred dollars. For that small form factor and image quality better than the K-5ii, it's worth trying, I think.
Good luck with your search
