Colos are expensive. $25 is dirt cheap for a colo. If you ever get
tired of the setup you have now,
you can get a Refurbished box from olm.net (and probably a lot of
other reputable
companies) for $30+ a month, but it won't have Remote Reboot at that
price. That's $5 a month

Sounds like the box is extremely reliable. Are you sure it is not
their Remote Reboot
that is not working properly on your box?

You are not using both Priorities and Protect Base are you? Use one or
the other,
preferably Priorities.
