The Premium PMS50 GNS750 is the best PLANE Instrument Bang-for-your-Buck addon for MSFS, as it can be used with EVERY plane, and on Every flight.
(May need to use the menu Pull down , in planes that do not support the GNS750 in their cockpit panel)
If in doubt, I believe there is an option for a Free Trial, that limits it;s operation on e specific day of the week
