How good is the U-HID G for pinball nudge functions? Is it responsive? Reliable? Any alternatives?
Using the 3 axes for nudge operations, it leaves 5 connections for 2 left, 2 right flippers and a plunger button, which is enough for pinball control. Does it support the "shift" function as the original U-HID does?
I plan to use it to built a Pinball controller...
See the link in my sig for my pin controller and U-HID-G settings.
It works ok for a digital nudge, but I never revisited to see if it can do analog nudging.
For analog nudging, Noah over on VPForums.org just recently released
VirtuaPin™ Digital Plunger Kit.

It's his answer to the older Nanotech
Mot-Ion kit that has some calibration, stability and heat-sensitivity issues.
Early reviews on the VirtuaPin Plunger Kit appear to be promising, but the sample size is still too small to be sure -- keep an eye on Noah's announcement thread to see how things shake out.

EDIT: Forgot to mention, but if you want to avoid messing with accelerometers,
KADE has a Pinball map that works great.
