I got mine from CPC Farnell for £35 including transparent case (which is awesome) and delivery. A few points: - only booted once on desktop, then used ssh and vnc only - used a cheap class 10 SDCard from a photo camera - Raspbian is very easy to use and update, just like a normal Debian but it only sees 256MB out of the box; to see the whole 512 RAM you need to download the new /boot files from git - use any smartphone charger (750mA+) - gets stuck in bios if plugged in a USB port such as router or laptop - not great as media player, server, router or desktop system; probably more suitable for DIY projects such as web cat feeder and home security
