I think that if you use companies it kind of takes away from the hobby IMO. Now I understand that some people just dont have the time to take care of a tank as a career comes first.

I have mine setup where I can go on a week vacation with one to two feedings. I rarely get any longer vacations than that at this point though. :(

Oh yeah and this brings up another big plus from maast- Other reefers are always ready to help if need be(maintenance or feeding). The networking aspect is a tremendous help if you need someone to cover you while you are on vacation.
