Another endorsement for mikrotik here...spent a lot of time in the WISP space and doing CPE installations. Mikrotik all the way down - text config files (version control), ssh-like remote terminals on all endpoints, full feature-set on even the most basic hardware. I've taken them into other jobs and other engineers have been happy with them.

The cons are that everything has one or more "mikrotik" way of doing things, and it may not be intuitive to the new user. Also, although everything is included, you have to set it all up yourself.
