Unfortunately the Sirius gear just seems to get more and more expensive particularly when you are "upgrading" an existing dome. When I bought my observatory I got the Maxdome system for dome rotation only and was shocked when I then priced an upgrade to powered shutter.
For reliable and reasonably priced long range wifi check out Ubiquity products. They make "enterprise grade" devices which seem to me to be more capable than consumer grade stuff. I made a rock solid connection over 1100 metres with their Nanostation devices which were only around $70 each (a couple of years ago). Many of their devices are 12 Volt powered and 12 power over Ethernet connectors are cheaply available (to get power to the external device from your Observatory over the same cable that will bring the network inside). Simple to set up if you have or can learn some basic networking skills.
