If you're near a college with an aviation department, see if there's
a way you can register for one of the sim courses. Local college here
has 12 Frasca, 4 ATP, an old DC10 that United donated over
10 years ago and 4 B1900 (don't know the vendor). Trust me, using a
Frasca is a couple orders of magnitude more effective than anything
MS sells. Plus, you get to count the hours towards the rating (which
you can't with MSFS).

Yes, it'll be mroe expensive but you won't pick up bad habits.
