i took the courses in nyc years ago. i was a nuendo user and always felt like i was slower than i could be at PT. now it is my main app and i love it to death. people can trash the course all they want but in reality, they really don't know what it is all about other than what they've read online. EVERYONE will walk away having learned a great deal. will it get you a job? probably not...will it make you VERY efficient at using protools? most definitely. i devoted those few weeks to diving in and studying nothing but PT and it was worth every penny. i'm not one to sit with a manual. i want hands on and someone who really knows the ins and outs to be there with me. i spend 5g's on a compressor or a preamp about every month or so, and so do most of us on here. is it really that expensive?
just know that no one cares or really even knows about the certification. do it for yourself but not because you think it's going to impress someone and you'll be all set.
