the ones that have sold have been sold at 135.95 with 6 still left to buy, maybe the large number is the sum of all the keyboards plus postage/packing.
I've seen a few things recently on Ebay that are vastly overpriced, I thought there may be some well known reason for it that I hadn't heard about. lol
Just had a look at the link. That is a ridiculously high price for a keyboard. I do note however that it is using Cherry technology in the keys. That is up there with the best as I can verify.
I am typing this on a Cherry keyboard that I have had for the last 17+ years; it is now on its 3rd computer and showing no signs of age(unlike me). I fully expect it to see me off this planet.
It is a bit steep I must admit but soooo nice. I do have to own up to spending just under £70 on a gaming mouse, but it is a very nice and useful bit of kit.
Looked for an 18.1 inch screen for my laptop on ebay recently, one seller had them for sale at £1000. asked them why it was so dear he replied telling me that he only had one in stock. local computer store quoted me £180 including fitting...
I think input devices that you are comfortable with are very important. My 17+ yr old keyboard cost me £50+ new and I have a Wacom graphic tablet & pen that cost £150.
