I bought my Realforce 88UB from https://www.verkkokauppa.com/ back in 2013. That is a Finnish webstore, but they were willing to ship it to me in Norway. I got a fantastic deal on it, €137 ($160), and I still have it. Verkkokauppa doesn’t seem to sell Topre boards anymore.
I bought my white HHKB Pro2 Type-S from https://www.amazon.co.jp/ when I was on a business trip in Sapporo. They had other HHKB in stock at a store I visited, but I really wanted the Type-S, so I ordered via Amazon instead.
I realize this is probably of no help whatsoever to anyone considering getting a Topre board, but I just wanted to tell the origin stories of two of my favourite boards
