While searching for the eBay deals today for ergonomic keyboard, I found this non-eBay deal. Free pick up in Sydney CBD or around $10 flat rate postage.
It is an excellent keyboard, with great reviews. RRP $129.95.
What may be more interesting for some is that OfficeWorks has it for $128
I will leave it up to the humble reader how to use this information ;-)
(Hint - I ended up paying $80.56)
I got a similar style keyboard it's very hard getting used to.
