Interesting topic. I'd let my ears decide about mods but I'd never destroy the value of something.That's just my own personal choice.
I also think I'd take a long hard look at the person advocating the mods. If it's someone qualified and highly calable like Jez, then great. Someone like the Lampizator guy: Fine too. If it was just some bodger who can barely solder and has to quote Wikipedia when asked a technical question, I reckon I'd avoid.
