I'd get the wand from William's and then use a O2 tank (20 cubic foot from a gas supplier) and flow meter regulator (like this one
). The regulator (linked to) allows you to actually set the LpM rate for the oxygen. The cheapo regulator you get with the full kit (from William's) has no way for you to know how much oxygen you're putting into the wort. Also, with the standard CGA 540 connection means you can use normal O2 tanks (from welding gas suppliers) and end up going through far less tanks/bottles. I used the disposable tank (with matching regulator) initially, but it didn't last all that long and had no way for you to know how much O2 you're pushing.
Just get some 3/16" ID Bevlex hose to connect the wand to the regulator and you'll be set. You should be able to get a swivel nut from the welding supply store that will fit the regulator and have the 3/16" barb on it. I got mine from them for my O2 regulators.
BTW, you can sometimes find the same type of regulators on ebray. But, with them being reasonably priced on Amazon, for brand new ones (most on ebray are not brand new) I'd just purchase from Amazon.
