Life In 19x19

Has anyone purchased slate and shell stones from YMI before? Most likely I'd go with the 9.2mm standard grade--for $224 or so, YMI seems to have the best price (with free shipping), but I'm not sure what the quality of their stones or will be.

I'd also like to get a set of Go Seigen bowls. Any opinions on these?

I believe they are Kuroki Goishiten stones. I have a set from KGT and am happy with them. Unfortunately for me, I bought mine direct from the KGT site and had to pay the shipping rates from Japan to US (PA).

I thought about purchasing those stones since the price is right & mine are size 28 but... nowadays 'my stones are too thin' just isn't justification enough.
