I have some of these I may be willing to sell. A Mac, a Matco, and a couple of Snap-On models. Not sure how much I would want though... More than a 6 pack of beer.
Here's one (Snap-On) on eBay for $39:

Hi Scott,
There are plenty of cheap ones on the market, but I was looking for a
recommendation for one that's reasonably accurate and has a dedicated
4-cyl setting. Just looking for the experienced answers.
The air bypass screw on the TB fixed the high idle, but it had to be
turned in a number of turns. Why, I don't know. Now the idle is nice and
low and does not surge. I'll have to poke around and see if I can find
out why the adjustment even needed to be made because it should not have
drifted that high by itself.
