Just to add my .02 cents, I view the training offered by Tab as a matter of opportunity cost. Opportunity cost being the value of something foregone for another choice made.
In my cost analysis, the opportunity cost of becoming 14,000/yr CFI for two years as a means of attracting an employer could potentially be greater than the cost of attending a four month program such as that offered by TAB. Factor in also what the CFI ratings will cost and it is a rather hefty sum; perhaps comparable or greater than TAB. Throw into the mix the foregone income that could have been earned in another endeavour.
Weighing the other side, a student engaged in King Air training and logging PIC time in turbine aircraft on non-revenue loft type routes, may well have lower Total Time but has gained a different experience that won't necessarily be obtained logging a greater number of hours as a CFI.
not selling the place...just a viable "choice" of similar "cost" compared to being an instructor.
