I purchased the Hyfix MGW310, I found it super simple to install and get up and running.
From unboxing to having the system up and running took under 15 minutes.
Installation on my roof was a breeze using the supplied hardware.
I would recommend that you upgrade your roof mounting solution if you live in an area with high winds.
There is currently a hardware issue that affects some units have a read of the following document and see if it effects you.

If you are going to install an aftermarket high gain antenna make sure you use AUX 1 port to connect it I used LMR 400 Coaxial Cable and remotely attached the ADS-B antenna to my tv antenna pole. This keeps the base station stable which helps you if you are mining Geodnet as well and live in a high wind area.
There are a whole host of online resources if you get stuck, but to be honest it was all very straight forward.
