Just an increase due to inflation. I signed up for their safety course a couple of weeks ago and between the time I printed the form, signed it and faxed...it went from $350 to $400. And I found out only when they sent me a letter in the mail saying they charged my card $400 instead of the $350. Still, a bargain. Same for the R22, at just over $200K it's the best deal going for a small piston trainer.
