Yeah, i looked into those, but don't want one that has a bottom that requires a clamped screen. The full gong one's are a lil pricey both on ebay and other sites. Then i saw a youtube vid of someone using an 18mm vapor whip as the tube, and thick glass 18mm nipple, or a bowl as a diy method.
I think i could diy this pretty cheaply with a extreme q bowl, an adapter to get a seal from the butane nozzle where it has the ribbed tube outlet on the whip/bowl elbow piece, and a long narrow 18mm tapered vapor whip. Unless i can find just the top nozzle attachment gong piece cheaply, other wise i think the eq bowl will work fine. Think I'll start another WTB for that instead so to not get off topic too much.
But if anyone has a small tapered end (not one that requires a clamp filter), or dual gong extraction tube they want to sell for under $45 shipped, I'd definitely be interested. I Just can't justify $70+ on something i can possibly do diy for a fraction of the price, and especially since i don't think they're worth $70 (the smallest dual gong tubes).
However I'd still like to buy one if someone wants to let go of one for ~ $50 shipped to get back on topic.
