I use a Maverick 733 for a dual-probe meat and grill temp thermometer. It works well. I don't like the stock probes for meat. They are identical, larger diameter probes, and they make big holes in the meat and are a little difficult to insert. Kinda like sticking a pencil into a steak. And the Maverick doesn't always sync the base with the remote unit first try, but I've always been able to sync after a few tries. It seems to be accurate, measured against my other thermometers.
My stick probe is a LavaSoft Javelin. $25 from Amazon, and it does its thing well. Folds to put in pocket, unfolds to take temps quickly (a couple of seconds), fold to put back in pocket. No backlight. I have an issue with no backlight. I've ordered a Thermapen M4 with backlight.
I would not use an analog oven thermometer to sit on the grill. They are notoriously inaccurate, and difficult to see with the kettle lid in place.
