Its all very easy to nit pick someone when they have taken the time and effort to put a very detailed list of the likely actual costs involved in undertaking the training. Me personally I would take those costs and add on a 10% contingency and work from there. if it comes out cheaper its a bonus. Be conservative, thats what aviation is all about. Unfortunately far to many people get near the finish line and come up short when they run out of cash.
Also how much will it cost you being out of work and for how long whilst you do the training?
