Rich, I understand and I respect your work and your feelings about that but you also have to see the other side od the medal:
If someone buys one of your refurbished consols he owns it. In this case he can decide by himself what's he gonna do with it.
Some of them keep it like it is and protecting it like the holy grail, others modify it to their needs.
Both cases are the way it is and there's nothing heretical on it.
When I see rich people buying very old cars and modifying it to the edge with golden rims, air scoops and sporty stripes I could puke too, but they bought it and they decided to (maybe) destroy the original, doesn't matter if someone took 2 years of restoring it to mint state.
Game consoles are build to play, so play with it like YOU want. I will also modify my old, good looking Vader with an pause module and that doesn't change my love to it in any way!
If you can't life with this fact that people doing other things than just gaming with "your" consoles you should think about to keep every single device you've repaired.
This is not ment to be an attack of any kind, just my 2 cents
