...and liked the 82139 meter so much from the first posts in this thread that when I found it out of stock at the Sears on-line store, I clicked the little box for "email me when its back in stock". I just got the "back in stock at Sears.com" email notification yesterday, so I placed my order. I had a decent meter already, but it lacked the duty cycle feature I've heard I'll need if I ever mess about with my fuel injection.
