I was there for nearly 2 years, I just left last summer after instructing there about 1,000 hours.
I think most of the complaints about the MX were for 5+ years ago before their current director of maintenance stepped in.
They are old airplanes, but they also got abused and beat up a lot. They did have a lot of down airplanes because they actually DID the maintenance. They don't defer or ignore issues with the airplanes. I never saw their MX doing anything unsafe, I did see a lot of time builders squawking airplanes for operator error though
I did their whole pro course and don't regret it at all. It wasn't perfect but they have some great instructors, a great director of maintenance, and an awesome chief pilot.
Oh and you FOR SURE want a car if at all possible. You are far more likely to go crazy if you are stuck at the housing and end up eating at the tiki twice a day.
