I am puting together a list of what I need to install a complete hai system (II or IIe). I currently have GE wireless sensors throughout the house with my existing NX8 system. Wondering if there are many folks using the ge wireless 42a00 receiver. This is going to be a big purchase and it's not like I can jump in a little at a time and try stuff out. Would like to hear experiences from users of the 42A00 unit, since I dont want to replace my existing sensors. I might consider the Elk M1G also but am not thrilled with the dual firmware issue on these if I use the ge wireless support. I don't want this to be a M1G vs OMNI thread though, really just looking for wireless receiver opinions. Thanks!
