I haven't bought one yet, but I think the Thermoworks Smoke or Signals would work well. If you buy a red, white, or blue Smoke I think they are 20% off really soon (today might be the last day). If you get their newsletter you will frequently find either 15% off on a flash sale or site wide sale. I really think the Smoke is probably the best all around for the price. Signals would be great, but that $200ish price tag is harsh. However, you can use 3 meat probes with 1 grill probe with it hooking up to wifi to push notifications to your phone. So in theory you could go run errands while doing a smoke and know if you need to get home ASAP or not.
