2 Bosch BOVs - $20 each
 

Two good Bosch BOVs. One of them has the body of a check valve cemented to it (no valve inside, flows freely, doesn't affect function). One of them is just a straight BOV. Both can be run recirc or full VTA, so long as your ECU will support it.

$20 each, $25 shipped.

Edit: Straight BOV sold. "check valve" BOV still available. $25 shipped.

Bumpety for the edit.
