Managed to get a series 3 dock for my x220 for just £15.00 +£5.52 postage now in place and mostly configured , best thing is it was in new condition and had an official 135watt thinkpad power supply!

Of course the switch over messed up my existing monitor set up but its a small price to pay for such awesomess (2 x DisplayPort, 2 x DVI, 1 x VGA, 6 x USB 2.0, 1x eSATA 1x Gigabit ethernet ports)
