Looks like you have found a good deal. I have an Oregon Scientific wireless I bought 5 years ago, the EMR963HG series, a home receiver unit, and 3 sending units, that do temp and humidity. It is still available, but sort of a back order thing, and more expensive for that.

BUT, there is a lesson to be learned from my experience with it. The sending units are particularly sensitive to any metal near by. I had trouble with these for 5 years, only to realize what the problem was when I put up insulation on my north wall that had foil in it. Sending units failed completely at that point because the radio waves couldn't penetrate the foil. Also, I have 2 units hanging in the GH, and the wires from hanging plants can't be too close to the units, or they interfere with transmission. Any time I have trouble with a sending unit, I rearrange its position relative to interior objects. I now have 4 sending units (2 alarmed) and a hardwired alarm. Think I'm ready for any GH problems.
