I'm really sorry I dodn't mean to jib you out of a sale but bintel have these new for $29 now

Absolutely crazy price, I bought one, it pretty much means they aren't worth selling/buying 2nd hand, most people keep them as their trashy star party EPs or give them to soemone starting out that might get some good use out of it.
