Regrettably, going to let some good ones go:
uchigumori 202x71x27 -$350 $300 $275
Bought from @ethompson so you know it's good. His description:
Sold to me as Ohira, but not completely confident in the seller… regardless it is a superlative quality stone that straddles hato / jito lines. Zero lines or inclusions on the flattened surface. High contrast kasumi. Only thing keeping it from being a $750-1200 stone is that towards the bottom there is su, significant su by the looks of the sides… probably easily dug like most uchi, but makes the lifetime quality of the stone uncertain. For a hobbiest you’d still have a decade or more of use before that became an issue. I was talking to Milan and he mentioned he uses 2-5mm of softer pre-finishers per year and he’s making and polishing a lot more knives than we would. Should have flawless stone for at least half the height.
2: Morihei Hakka Suita- $500 $485 (850 new)
Description from Strata:
Brand: Morihei 森平
Producing Area: Kyoto - Japan
Mine: Hakka
Strata: Suita
Appearance: Beautiful off-white-orange with lots of Ao and Aka Renge
Size: 202mm x 76mm x 38mm
Weight: 1384g
Grit Range: 6000-8000
1-5 Scale: 1 = Less, 5 = More
Hardness Level: 3.5
Scratch Depth: 2
Speed: 4
Wear Rate: 1.5
Self Slurry: 2.5
Ease of Use: 3
Recommended Usage: Frosty to polished Kasumi; very keen edges; pre polishing for razors and tools.
Notes: A beautiful specimen of rare Hakka Suita. The corner line can be felt, but does not affect performance. The small pits are stable and do not scratch. Otherwise flawless. Really fast scratch removal makes polishing the Hagane a breeze, and easy to get a nice polished Kasumi quickly. Works best with forced slurry or tomo nagura, and mild to firm pressure in very short strokes.

3. Last but not least, Maruoyama Shiki-uchigumori Gokujo $500 $485 (new $608+shipping from japan)
197x74x48mm
A big one. I'm writing my own description and I'm not an expert so take everything with a grain of salt. I call hardness about 3-3.5. Quite fine, 6-8000 grit? While feedback is a little harder/chalkier than the first uchi for example, it slurries and cuts quite fast. Gives super punchy kasumis, very dark misty finish if you want to, or use more pressure to get something brighter. As you can see, has a small corner missing in the back, but it's a massive and extremely clean stone. Also known as tenjou suita from other mines, shiki uchi is unique to maruoyama. I think I can call this sunashi, don't really see any su holes..
