Ive had heaps of experience with them all, it depends what you're after.
I don't like the low end EEE PCs as they're too small a keyboard to type on if you're a touch typist like me but I found I could type normally fine on my daughter's Acer Aspire One.
Having said that my mate at work picked up a EEE a couple of weeks back on catchoftheday for $199 which is an incredible deal (virtually no HD but he bought a 32 or 64 gb stick to put in it).
Go to somewhere like Radio Rentals or Harvey Norman and have a play with them, some of the lower end ones have shockingly small screens, find what you like and then go purchase it online cheaper!
I personally would like one with a built in sim card so there's no mucking about with external modems, I think Virgin or Vodaphone do a deal with one like that.
My daughter has had no probs with her Acer Aspire 1, I know another lady at work who loves hers too. My mum has two EEPcs and had problems with at least 1 from memory, it was under warranty but meant a bit of stuffing around.
