I'm on the fence. The price is not so much an issue. They're both ridiculously expensive and if I'm spending over $300, I want to do it once. (I only have one large BGE... no plans for more)
Here's what I think I like about the Stoker that I don't think the CyberQ does:
It's got an IP address... I can plug a wireless adapter directly into the Stoker... and I can control it from my phone.
If I'm reading the CyberQ manual properly, I need to hardwire the device to a PC (not a Mac, which I have)... that's a problem for me as my PC is other end of house... and I'm not clear that I can control it from my phone even in that case, though I suspect I could.
Here's what I don't think I like about the Stoker. It seems as if the pit temp maxes out at 450. That's what drives me nuts about the ET-73. When it maxes out, I don't know if the dome temp is 450 or 700.
Other than that, unless there's something I'm missing, I think it's 6-o-1-half a dozen-o-another.
