Trouble is these are really cool, but the weak global economy has all but stopped sales of anything "extra". In former times, I'd have been all over things like this- now so many of us are fighting to keep our electricity on and a roof over our heads that these have fallen prey to those who have extra money. Since the times have become desperate, the market has narrowed considerably. Those with some extra money have their pick of whatever those of us who are less fortunate must part with- at bargain prices, because we need the scratch. Such a special interest piece would have a limited market to begin with, then add in how many folks who are still financially well off would be interested in an old derailleur... Thus prices have gone to hell with the economy. Hard times..
