A full set with no fluros or golds is probably about $15-$20. Fluros are worth probs at least $3 each.
BTW I'm basing these prices on what I get and pay for them; if you go to ebay they are MUCH more expensive. (Gold= $20, Fluro=$10, full set no extras=$30)
Lol I wish I could tell you the prices were less so I could scab them off you, but I'm not that much of a dick XD
