Reply to VCI 100se vs. VCI 100se Arcade Edition

I have done alot of digging, but there is SO much information on here, and alot of the time it's not what I'm after.

(Yes I realise my post count, and I realise others may tell me 'use the search function' .. but I was really hoping the you djtt'ers could give me a hand here as I have indeed searched)

At current, I am in the market to buy a VCI 100se Arcade Edition.
However; Apart from the fast hitting buttons for set cue points, I would like to know the DIFFERENCES between the 100se and 100se 'arcade edition.'

For instance.. is the 'Play/Pause' button on the normal 100se the same as the 'arcade edition' ?
Are the only differences the actual buttons themselves?
Do eangolden's mappings gains/lose features when upgrading to the 'arcade edition' ?

I would really like some USER FEEDBACK here, from those who have used one of these, and those who have used both.
Basically I want the feedback to be able to make the right choice for myself.
At the moment I am leaning towards the Arcade Edition, as I know I'm going to use those fast action fighter buttons, but I would just like current users feedback.

Thanks heaps guys!
