Campagnolo Pista (C Record) crank set

To be honest, I do not really need it and it's also not "vintage" or "classic", but if you can buy such a crank set for just a "small" amount of money, you simply have to get it.
Now the big question is: will I keep it or resell, to make some $$$ and buy other stuff, that is on the wish list ?
Maybe it will go on my Giant bike, so I can put the old Record crank set on the new classic bike.

170mm, 51T, 50 km used but I can't see it.
Anyone interested ? It will not go for less than € 150.- and even for better offers I have to think twice.
