A couple of weeks ago, precisionbooks started popping up on eBay.com. I bought one of the first with buy-it-now for $249. A couple of hours later the seller terminated the auction and put up a new auction for $499 (the first auction was a Dutch auction with 30 precisionbooks :). I believe the price now has dropped to $349. If you look at the other auctions of the seller, it looks a bit shady, but I got my portable in good condition.
The precisionbook is much more portable than the HP K210 I previously was using (which is for sale now btw; it will pop up on eBay.de or send me an e-mail). From software the precisionbook looks just like a B-class, it runs all normal applications. Only the graphics card isn't that great; some 3D acceleration would have been nice.
