Well, the installer is supposed to be here between 1 and 5 and here it is 1:42. Watch him come at 4:30. I'm going nuts waiting on the guy to get here. I did get the automated call from Mastec yesterday, so I'm hoping that means they do have HR20's here in DFW. I've read a lot about them being out of stock. Fingers crossed. I'll chime in with my thoughts after install.
