The point concerning TR revalidation is an important one, certainly worth considering. It might not be much of a bugger for as long as the owner or operator is footing the bill for you - but what if you lose your job and have to either do it off your own back or end up without any valid type rating on your licence? To begin with, simulators for most business jets are not as widely available as the ones for the A320, B737 or some other popular type. You might find out that the only one in the world is in the USA - and then this starts getting expensive even before you have paid a single cent to the training centre. And, once you've travelled half of the globe for your LPC, you'll get charged an arm and a leg for the actual check simply because the training centre has a complete monopoly on this type and you don't have anyone else to go to for training.
