You get what you pay for. Subaru spent an outrageous amount of money developing the powertrain in this car. Using substandard parts would be foolish. I've been working on japanese cars for 10 years, and I use factory parts. That should tell you something. Don't buy an aftermarket thermostat, that's one of the worst parts to skimp on. There is a major difference between aftermarket and factory on thermostats. And while you're at it, Subaru uses a coolant that has a special formulation. I'd check that out.
