I have both. I like them both. The iGrill works well especially since I can use my phone or ipad. I wanted a temp probe and two meat probes so after using the iGrill I found a good deal on the 732 and bought that. If you only wanted two probes, I would just get whichever is less or the iGrill since it has two meat probes. Yes one of the meat probes can be used as a pit probe.
