Adam,
I picked up a 721 last spring at the ETF Convention. I'm really anxious to get to it, it's next up in the in-basket after the Haunted Roundie Admiral from Hell. I thought I might do another step-by-step series here with it, but you beat me to it
I'd be happy to doublecheck anything on mine if you want, and compare notes. Datasheet is SAMS 70-7, I have one handy.
