So I'm trying to decide which would be the better combination and my question is this: If the minipac does basically everything that the I-pac + Opti-pac does why would I want to spend more on the two separate boards? I know that the Opti can handle more spinners/trackballs than the mini, but for the average cabinet wouldn't the mini be fine and cheaper? On a related note, is there a provision on the mini and opti for the mouse buttons? Thanks for any help for the newbie! -Malcolm
