I would highly recommend DIS. The techs have been amazing in working with us with the installation of new towers and a new server. They are professional and we have no complaints. They've returned my calls and worked through the software issues that have popped up in a more than timely manner. I enjoy working with DIS - they are always accommodating and answer questions as they come up in a manner in which I can understand.
