who makes a good wideband?

Well when my engine blew in January I noticed my wideband was getting the 3 dashes on the gauge again. I figured the cable disconnected again but I didn't worry about it until recently because I had so many projects going on. I was incorrect. All the cables are still attached. I swapped in my old sensor and I get 3 dashes with it too. So either both sensors are bad or there is some other problem I'm not seeing. I went through and checked my wiring and I'm not even sure how this thing ever operated to begin with lol. For some reason I had the system ground and heater ground spliced with a wire going to some "control box" (the little black box next to the ECU) and there are no wires coming out of it, so I'm pretty sure neither of those wires have been grounded for the past 3 years, yet the WB was still working. Hmmmm. I've also had the yellow wire hooked up to AN2 (or AN1, I don't remember which) on the Datalogit, and apparently that is the heater wire so I'm pretty sure that's wrong too, but I'm not sure where to hook it up. I'm going to call Innovate again but at this point I'm leaning towards getting something else. I just got my engine back in and started and I don't know what the AFRs are, and even though I'm only breaking it in for the next 1500 miles and not boosting, I still want to know what the numbers are during this time.
