Hi.

I am thinking of purchasing either a KN1400 or a KN920 secondhand. Could anyone who is familiar with the Australian keyboad market advise me on what would be a reasonable price range for these (or similar) models in Australia? Assume that the keyboards are in good condition and full working order.

Failing that, is there any general 'rule of thumb' for determining the approximate price/value of second-hand keyboards, Technics or otherwise?

Thanks.
