Good on you for shopping around - knowledge is power in making an informed decision.
However, consider this: a Beech 1900 is a
turboprop with less than 40 seats. So, if any one is going to charge you $10,000+, ask yourself what do you get for the 10G? Just the type rating? Is accommodation and manuals included?
The reason I mention this is that you can get a
turbojet type rating for FAR less eg. B737 for around $6000 (basic -200) or a Citation for even less. Why in the world would you want to fork out that kind of money for a turboprop? It's like the company (who shall be nameless) that once advertised for pay-for-own-training as a condition of employment for a J31 FO position. The catch was it cost you $7,500 and for that you did not even get a type rating but were "guaranteed" an interview!!
Maybe after graduation, they "offer" you time in type as well? Ask lots of questions including what you get for the price. Be very specific and if they hesitate, move on. My first question would be how come it costs more for a B1900 than either of the jets mentioned above.
Last but not least, the training organizations like FSI are always going to be the most expensive because training is their bread and butter. And judging by your final post, British, it seems like you have stumbled on what I am trying to say here ...
Just curious...do they do B1900s with a title like 737?
