That makes sense. It is definitely an investment, especially with Cherry MX switches. I think there are competitors to Cherry MX silent reds, though, and there may be some competitively priced boards with those non-Cherry switches.
If you feel like diving into that research a bit, the subreddit for mechanical keyboards is pretty informative. Here is their buying guide. Some entries on the budget list have prices that are very comparable to the Perixx, although I mostly see reds and not silent reds. But maybe with some more research a mech with silent reds could be found at that price point.
Good luck!
Oh, and @non-jedi: To my ear, the release of a fully depressed key/switch is effectively silent. It is more the keycap smacking the actual board that was the secret source of noise, I thought.
