1200 psi is good enough. Your gun won't get 5k psi, it's not even possable. A good/cheap mask would be a JT Alpha, if they ever fog up, just replace the lens with thermal lens.
If you want to save some cash, just buy a used Imagine. That's what I did and then I just upgraded the hell out of it and I still am. In fact, I'm converting it into a LP marker.
Yet, I do still crave the high-end marker. My eyes are currently set on the XSV Ego once I'm done with my Spyder and have enough money to buy it.
