Okay it's probably been debated before so please forgive me.
I've owned both throughout my life but now instead of playing emulators, I want to buy a megadrive again.
So what differences are there? Not sure how true this is but I've read megadrive 1 Rgb scart works better than a model 2 with Rgb scart. Also the model 1 has stereo sound through headphones ( I'm not fussed as won't be wearing them ) but I've heard model 2 is less likely to die??
