Stall, I dont have any schools I can recommend (having never used one etc for a sim)
What I would say is a couple of things; first of all when you do go for a sim check, unless you have experience on a particular type of T/P the instructor will be looking for you to do the basics well, for that you dont need a sim..FS2000/02/04 will do it just as well.
Secondly, even before you shoot off to go and book a sim etc...I would suggest you try to beg steal or borrow a copy of the sim profile, thats if you can get your hands on it!
I hope this helps
