Kin is not a knife maker, but a knife supplier, and I'd say their prices in general are nothing special. A lot of their knives will be rebranded OEM items. I have never heard them mentioned on kitchenknivesforum, so that maybe tells you something. If you live in Europe there is Japanesechefsknives.com and a few others. JCK will certainly have everything that Kin has, in one form or another, and more.
What exactly, if anything in particular, are you looking for in these knives you're considering? That is likely a better question for you to ask.
