I have a set left from a project. I bought them used and they look functional to me, however, I have never used them.
They are selling new for around $80. I would sell them for $40 plus shipping (at cost).
If you also need the intake, I'm selling the set for $60 (check my FS post).
Both for only $90 plus shipping.
PayPal is OK, but you have to pay the fees.
PM me if you need more info and if you are interested.
