I was wondering if Alts. Camshaft is still somewhat rare ? If so, what would be the average value of one (say a MISB one) ? I was planning to trade the extra one I got today for maybe Alts. Mirage, would that be fair ? Also, my TRU have plenty of Classics Starscream, are peoples still wanting him as much as before ? And again if still rare, what value would he have on average ? Maybe I could buy some extra for trade.
