Well the pressure clean should cost you like $30 im running a modified FC and the radiator is still fine. If you feel like blowing cash sure go out and buy a new one. But I would be getting it cleaned first. And did you put a genuine thermostat in, aftermarket ones have been known to cause problems

Is the car for sure overheating? Is the coolant bubbling into the overflow tank and spraying out onto the ground, or is your temperature gauge just going up higher than normal? The stock gauge can be unreliable.
Make sure you have the stock fan shroud on the radiator. The underpan is also a very good idea, though driving with mine off for a while didn't cause my car to overheat. You also said the thermostat was recently replaced. Make sure it was a new OEM Mazda thermostat. Make sure your waterpump spins freely and that the belt isn't slipping. If this doesn't help, take the radiator out of the car (4 bolts, real simple) Stick a garden hose in on full blast. That's how I unplugged a big clog in the radiator of my TII when I first picked it up.
If none of this works, I will come give you $250 for the car

Either get a new rad. Or simply, let your car get to operating temp. then drain the rad then refill it, (dont keep putting anti-freeze in it, just use water untill your done cleaning it, this can take a few days if needed. Keep doing this process untill its cleaner.
