Heh, yup, I'm the smoking nerd who buys every supplemental product for "scientific purposes". ;D
Here are the ones that I use ... the only reason I chose them over the Steve Raichlen gloves on Amazon is that these are black and are more resistant to stains:

If you've got Amazon Prime, I had a set of these that lasted several years and were very good for the money; they do stain but a quick soak in white vinegar fixes most of the problems:

Both sets of gloves are long enough to go well past the wrist and fit even big paws like mine. I'll just pull ribs, briskets and butts out of the smoker with them to transfer to a meat pan and the heat isn't an issue. There are some mittens style that lack the individual fingers that I'd avoid ... rendered fat is a slippery thing so every little advantage helps.
Hmmm ... perhaps I need to have Ben create a Gadgets listing so we can all post our gear reviews ...
