in all seriousness i was watching a set on ebay. i think it was a UK auction. they went for like 310 pounds for the front and 200 for the rear (around $720 total)

personally i think they went for an insane amount. I would personally pay maybe $300 for the set, but some people pay crazy prices for things i don't understand (i'd compare them to old aerospokes, which also often go for way more than i'd think is appropriate)

dunno what the market in luxembourg is like. i'd expect here in CA you could list the set for $500 or so and sell it.
