Before you send a stock unit to be modded, make sure it is going to fit the needs of your system well into the future and expect to get the value from using it. You probably won't recover the cost if you decide to resell, but the real reward is from listening.
One other point about SMc mods that may have not been mentioned.
There is a three year warranty on newly modded amps that a buyer is not getting with a used unit. That may influence some to get their own gear modded rather than buy used.
The same can be said of other hobbies. Try selling a customized 1911 pistol and recovering what it cost. You can buy a stock pistol, new or used, and easily double or triple your investment with refinements and custom tuning. You end up with an awesome handgun that is like a work of art. It would be rare to find a buyer who pays anything near what you have into it.
