ERAU-Prescott
I instructed at Riddle-Prescott during the late '80s-early '90s, so some of what I may have to say may be dated, but I doubt things have changed much.
Upsides and downsides: A very stimulating learning enviroment for everyone, but quite a bit of bickering and quibbling over small points. Well-maintained aircraft, but not enough of them to handle the student load. Decent pay, if you can keep busy, but if you can't get aircraft for your students you'll be SOL. There are peaks and valleys of aircraft availability. Now, if you can stay busy, it used to be that if you racked up at least 1000 hours of contact per year, you were paid a bonus. I don't remember the exact scheme, but it was very generous. One of the flight line ladies who was absolutely super once told me that she didn't understand why more people didn't make bonus. Contact hours included flight, sims and orals. If you made it to stage check pilot, you were paid a salary that in my day was competitive with a new commuter captain's. Very fair. Benies were adequate. I don't remember if there was a 401-K.
Another upside: If you upgrade to the multis and you're in the right place at the right time, you'll build a ton of multi quickly. I started off a school year with 65 multi hours. By the end of the second semester I had something like 540 hours of multi in my logbooks. This is significant because in the early '90s you needed at least 500 hours of multi to qualify for the commuters. You just may need that now when hiring picks up.
More downsides: The place is very political. There are some big egos and major turf-protectors at Riddle. There used to be a lot of tension between the flight line and campus. I feel that these battles impacted on training. Also, it was hard to get a straight answer to questions. You would start with one person, who would tell you to go to another person, who would tell you to go to still another person. That was known as the "Riddle Runaround."
I just got my issue of the AOPA magazine and saw where Riddle is advertising for instructors. I realize these ads were placed months before 911, so I wonder if the school really is hiring and the ads haven't been pulled. Doesn't hurt to check.
Hope this helps a little. Good luck with your job search.
