Well, I've been at ADP at the end of the last year and recommend them.
Airplanes are quite old but maintenance is good (like described above), rates are very competetive and the location of ADP/Brackett Field is ideal.
LAX, Santa Monica, Santa Barbara, Van Nuys, Santa Ana, Palm Springs ... every place within half an hour or one hour. Complex airspace structure.
Much more fun and experience than for example in Arizona; Phoenix, Tucson etc.
Have fun!
