I was attending Airline Training Academy. I know that tends to be a nasty phrase around here, but at the time it worked for me, especially since I already had a private license and didn't really have too much time to build for an instrument rating. The airline prep portion of the Academy was really the only part I could recomend, although I got lucky and had a great CFII and MEI. Having the possibility to interview at 400TT, if you know what you're doing, is what obviously draws most people there.
