and on a parallel but slightly unrelated subject, i bought a second hand speed controller for an RC car. Absolute top end kit, retails at well north of 200 quid (if you can find them, rare as rocking horse shit in europe.) The chap wanted 35 quid, inc postage. Bargain.
Turns out its still brand new in packet with all the manufacturers seals in place, upon opening it turns out is had only been manufactured 6 months ago.......
That certainly put a smile on my face.
Bought another speedo from someone else a couple of months ago. 60 quid inc postage for a 200 speedo, marked as "used".
Only reason it was marked as used was that he'd opened the packet, realised it was far far too big to fit in his car, then sold it. Hadn't even opened the bag with all the cables in it.
