I've searched the forums before I asked, thanks for the links, but these also don't have specifics. I guess we don't have native Jap forum members?
If you haven't noticed, Hasu (whom posted a reply here) is from Japan or at least he supplied his location as Japan.
Most people probably ust get them from eBay. I did
I also got mine from ebay as well, at the time I was unsure of the proxies plus I am not too keen with buying stuff from other (or in general unfamiliar) websites. I paid a premium price for my Type-S (still waiting to appear in mail). Having a proxy to do the work on your behalf is totally ideal if they (the proxies) does not overcharge you. Nonetheless you are free to shop around to get the best price.
Not sure if this proxy service was mentioned but there's a website called tenso.com which will do purchasing from sellers whom does not ship outside Japan to have it shipped to you. I haven't tried them yet and the site was mentioned by rakuten.co.jp.
Slightly off-topic, but why is the HHKB so expensive anyways? I get that topre switches/keyboards are expensive, but this is a 60 key board. How is a 104 key realforce more expensive? You'd expect less switch + smaller board = lower cost for material = lower prices.
I tend to say that maybe HHKB is trying to ride on fame. It's noted on wikipedia for that matter. Then again I'm more or less quoting what others have said. Then again what others have said could/may also be potentially true as either part of completely the reason behind expensive price tags.
