Anyone know of a good deal on the 2 to 3 inch type circular flow rite snap in inserts? You know the ones that just take a hole saw cut out, then snap the insert in and there ya go... I know SLP sells them (see link below), but seems pretty pricey at $21 per insert. Gotta be a less expensive vendor out there, or can you find the materials at a hardware type store and just put em together. Looking to add some heat venting here and there. Thanks...
