well, i think his listing is a bit naughty, but still, he's not doing owt wrong.
he put them as an auction and market forces being what they are he's got £155 for his flights. he didn't force anyone to buy them.
Its a funny old hobby really, if the "enthusiasts" on here say "oh MX1000 set? NOS? oh that's worth £200 easy" then that's fine and no one even says a word about it, but someone does the same on ebay but with a (according to the gods that are RAD) slightly less desirable...all be it a better working, set of brakes...let's say for example...901s...then suddenly it's out of order, and wrong, and they were only £40 last week, blah blah blah.
At the end of the day if you have something for sale and you don't actually lie in the description then it is worth exactly what someone is willing to pay.
Now if any one of you found a box full of NOS DX pedals and a box full of MX1000 brakes for £10 each would you:
A. punt them out here for a small profit and benefit your "mates" on RAD
B. sell them for the aboslute maximum cash you can get from them and to hell with your "mates" on RAD.
I know it;s not the same, as seeling somehting rmodern as old, but it's still marking something up vastly and you would ALL do it!
