These are the ones that I've come across actually in stock in my area (Perth).
The Co-op bookshops (found at various Unis round the country) sell BeBooks, BeBook Minis and Neos. You don't have to be a student to buy there, and they told me that you can become a member for a one off fee of $20. That gives you discounts.
Bebook Neo at Coop
We have 4 devices that we read books on, and all were bought from local shops, as I prefer to be able to see before I buy, and also to have somewhere to go back to in case of problems. We have been pleased with all of them.
1.
iTouch good price at JB Hifi (and numerous other places). I bought it for music but was amazed to find that I've been able to comfortably read several complete books on it.
2.
iRiver Story from the local Harvey Norman store. They knocked off 8.5% ($33.00) when I asked what they could do for cash. My wife's current favourite.
3.
Acer 10" netbook. On 'special' at the local Coles supermarket, although the reduction was small. A good little computer for under $400 and I find it easy to read on. The display can be turned to portrait mode.
4.
HP Touchsmart TM2 12" tablet computer. Already reasonably priced at Dick Smith, they knocked another $100 off for the asking. My favourite device for all reading - it's big enough for PDFs, online magazines and news sites, forums etc and gives a good big page for reading. You can instal software to read whatever formats you like. The touch screen folds back over the keyboard to make a chunky and versatile tablet.
Cheers,
Chris
