I was there last Sep after I got the call from SWA.
The short version is that "you get what you pay for". Not as good as I understand Higher Power and K&S are but gets you a type. I went there because I already had been interviewed at SWA and once they called me I figured I would get the cheapest type I could find.
The biggest problem I had was that they took forever to send me the material, it finally arrived only a couple of days before I left for DEN. I had to cram everything as quickly as I could. Make sure they have your correct address and call them EVERY DAY to make sure they sent you your stuff, it has happened often I was told later.
The ground portion was straight forward and the instructor did a good job in the short time we had to highlight the important stuff.
The sim part was not too bad but the -200 United sim has a Sperry 77 autopilot: it's the oldest piece of crap ever. You'll see what I mean.
The sim instructor was a Continental captain who lives in the area. Good guy but didn't care too much about the whole thing, was on the phone the whole time we were flying.
The great thing is that UAL does not use that sim anymore and FTI is the only outfit which uses it. On your off time, like in the evening and at night, you can just go there and practice. My sim partner didn't care much but I still managed to convince him to go a couple of times. I thought it was great, free sim hours = free money in my book.
The oral and type ride were just as we expected, no curve balls. Overall an ok experience exept for the office ladies who are a bit challenged in the admin side of things.
Good luck.
P.S. If you stay at the Crown Plaza (or whatever is the hotel they have the office in) be very careful where you walk to. I think it was a United pilot who got mugged just a few months ago, if I remember correctly he got beat up or even worse.
