Hi Richard,
I've evaluated the GL-iNet SFT1200 and MT3000 routers. Either would be an excellent choice. The MT3000 has more transmit power and manages to get a 30+mbps connection through a couple of masonry walls in my house. The SFT1200 gets about a 10th of that, which in my experience is not enough for return preparation. If you have a single relatively unobstructed room, the SFT1200 is a good inexpensive choice.
[Edit: Note that the above tests were done in a room in my house where WiFi signal strength is notoriously bad, and are intended only to show that the MT3000 has a much stronger signal than the SFT1200. Tests from other rooms showed excellent data rates, in excess of 30Mpbs. My first choice for the nine sites in D22 would be the SFT1200 because it has a better price point.]
Bonus features: except for the DHCP address range configuration, the two have identical configuration screens. If you know one you can manage the other without breaking a sweat.
The second: if you are WISPing, the routers remember multiple uptream connection configurations and cycle through them looking for something that works. One could configure each router with the WISP parameters for each site in D04. They will then be interchangeable at sites that use the same Tax-Aide net IP address range. If I recall correctly, they can be configured to ignore any WISP WiFi nets when connected via an Ethernet cable, so the cable'd sites join the interoperability pool.
Sites with multiple firewalls might need a bit more thought.
Also, the configuration backup is a zipped tarball of plain text files. I have it on my todo list to see if I configure one router for all of my sites, can I just cut and paste /etc/config/wireless into the config backup for the other routers in my district and have them work?
Good luck
