I mean there are differences between the mkI and mkII, mainly different filters and the mkII changed from triangle to saw wave. They are both strong semi-modular units so you should understand why you want one and how the differences between the models affect what you want to do with it, because buying a piece of equipment based on how someone else uses it is not a good indicator of what you will be able to do with it. I have an mkII and I like it fine but I'm not entirely happy with it. It can certainly be absolutely punishing on a proper PA once you wrap your head around using it.
