Hi all

its me again. So I have decided to get the m300 but only qualify for the ps so I was wondering what's the difference between the ps and corpus 3G?

the obvious answer is the seating. Which I was told I would get a ride forward cushion and I forget which kind of back. I wasn't that impressed with the back I tried so can anyone recommend a good back that is compatible with the ps?

plus any reviews on the ps would be greatly appreciated
