no regrets at all! i love it!
we've been playing plenty of golden tee and world class bowling,
also dabbled with some horsehoes, and darts games as well.
all in all IIRC there are about 75 titles currently in my collection thati can use the track ball on.
the aimtrak bits came in, and ive built one gun so far, but having troubles withsetting itup to work correctly,
once i sort that out ill be set!
