The injector is from Lakeland an online uk kitchen store. I bought so much at their flagship shop last summer whilst on holiday, that my parents had to cart home a lot of our luggage in their car
The Stubbs bottles are HUGE. I found them in Costco. I may actually have screamed a little at finding them as I haven't seen Stubbs stocked in at supermarkets for years now. I have about 8 bottles squirrelled away as the best before date is 2016. Last year costco stocked Cattleman's classic, but I much prefer this
I'd take Stubbs over Cattleman's any day. I'm not a big fan of Cattlemans as my folks bought a giant bottle of it last year and poured it on everything till we got sick of it altogether. But I rank Stubbs in about the same catergory as Tony Roma's, Kraft, or Heinz barbecue sauces - which is to say they're OK for a general purpose sauce but still fairly ordinary. I use all of the above for "doctor" sauces, though - they're a good base to make your own sauces from.
Where I really have a lot of fun is making batches of sauces from Steven's books and then canning them. Since most homemade sauces have a lot of vinegar or other acidity they can usually be canned in a boiling-water bath instead of a pressure canner. It's great to spend a couple of hour in the afternoon cooking 4 or 5 batches of sauce, and then storing them up for later months, too. (One big tip - if you can find the canning jars with the glass lids and a rubber washer, they last longer than the metal jar lids, which can corrode because of the acidity.)
As for that injector, I changed my mind as I happened to find a spare tube of epoxy. I tried filling the cracks so we'll see if I can fix it well enough until I find a better one like yours.
