EDIT: Mixed up two adverts looking at them at the same time. Have just realised that these are missing all the faceplates so not such a bargain if you want the units complete. I've left the original post below should anyone still wish to check them out.

At the time of posting this UK seller has 6 
Cisco 2811 routers at £14.00 each delivered (they're actually £9.00 each + £5 P&P but I think you'd have to be pretty cheeky to ask for a discount when buying more than one).
I've paid between £20 and £35 each for mine so these are a bargain. At this price why even consider anything older!
