The MAPD program actually does manage to get about 80% of it's students jobs at Mesa. This is a higher success rate than many other similar programs. It seems to be a high-quality program also.
However, like the other guy said there are numerous advantages to having CFI ratings and experience. Also, if Mesa were to downsize or stop hiring the MAPD training (and $3.20) will get you a Latte at Starbucks.
