So that's the only real difference? That seems more than OK to me to just go with the Ultimarc one then. Does anyone use the Ultimarc products? This is what I plan on ordering, is it any good?
2x T-Stik Plus (1x RED, 1x BLUE)
18x Pushbutton (6x RED, 6x BLUE, 1x PLAYERONE, 1x PLAYERTWO, 2x BLACK, 2x YELLOW)
1x iPac2 Interface (PS/2 CABLE)
Does anyone have any experience with these products? Also, about the Trackball, should I get the Opti-Pac cable? Also, is there a way to use the trackball without having to connect an Opti-Pac?
