I was about to order an I-PAC and an Opti-PAC from http://www.ultimarc.com/JShopServer/section.php?xSec=2
but I wanted to ask what benefites or troubles would I run into going with these

What I am looking at is this,
I-PAC 4 Interface. - 56-Input button/joystick switch interface. USB or PS/2.
(cable can be selected when adding to cart)
Shape D.:
it doesn't really matter too much but if you have usb just go with that.

I have an Ipac4 and it is hooked up USB.

Bad info - The opti-pac has two Ports, each one can handle a trackball and/or two spinners, the  unit will auto-switch between spinners/trackballs on the same port.  Two trackballs or 4 spinners can be active in either mode.  Two trackballs AND 4 spinners are not supported (all active at once).

In USB mode, the device works with recent MAME builds in 98SE or a fairly old build on Analog Plus in XP.

In serial mode, the device works with DOS mame with two different Mouse drivers.

(I think you can use two devices in serial mode with Analog Plus and XP, but can't think of a reason to.)
