richms: I should get some old models ordered before too long, as I have a couple of half finished projects I have pillaged the pi from to do something else with and dont want to have to re-glue the standoffs to hold it etc.Sounds like you don't have to hurry too fast:
"We think you’re going to love Model B+, but to ensure continuity of supply for our industrial customers we’ll be keeping Model B in production for as long as there’s demand for it." - http://www.raspberrypi.org/introducing-raspberry-pi-model-b-plus/
That said, is there any real reason to hold off? :)
