Overall they are still cheaper. But IMO not cheap enough to make them worth it.
As much as I was against the use of resistors too...many OEM's do it, so it obviously isnt as bad as it sounds.
But with MS you are tied to using the Ford EDIS ignition system. Which I guess is ok.
Just depends what you want really. I prefer just to buy a quality product that I know works and there is support for.
Everyone who has MS says the support is great too though. But it seems a lot of features require extra code and there is lots of software fucking about to make stuff work.
But even a fully build MS3 does seem to require extras to achieve basic stuff that other branded ecu's will have already
