I got these some time ago mainly just to try as they're both intended to replicate natural stones and I was curious. Both good stones.
The JNS Red has a good size and is listed as 2k-4k. You can read more about it elsewhere or here.
On the other hand, I have no idea if anyone who reads this will have tried the Renge Suita, and so I'll say more. I ordered it from Japan where it seems to be popular enough, and it'd be a surprise if this one wasn't stocked by any overseas sellers. The kanji says 'synthetic renge suita finishing stone' and it's listed as 6k. Nice feel/feedback which does well in replicating the knife-friendly Ohira suita I have tried, not the too-hard-for-knives harder suita out there. It isn't too fine, nor too hard or soft, and leaves a natural-like hazy finish with good jigane/hagane contrast. I was pretty happy with it and I think it's an economical option if you want to try something like a softer knife-friendly jnat suita, to be assured of good results, but also if maybe you don't have the budget to try this kind of jnat finisher.
I'd like to sell both stones together to minimise shipping and fuss, unless someone is interested in combining one with the nagura I still have on BST here or 2 or 3 others I haven't got round to listing yet. (PM me in that case.) With the grit ranges these have and the results you get from them, I also think these two compliment each other very well. Asking $180 for the two together shipped & insured.
Note: JNS Red was a bit damp during the photo, hence the inconsistencies in colour. Also, the kanji is intact on both because I tried them on the underside.
