They have a special now on them--order at educator's price of $89 before Sept 30 and you qualify for a $20 refund once you "prove" you're a teacher (through paystub or whatever).
I've checked prices on ebay and this seems to be the best price going. While I'd still love to have a larger tablet, I think I'm going to try this. I'll let you know what I think, and I'd love to hear from others who are already using them.
This site also has really good prices on software with the education discount. Soooo tempted :-)
