DIY Self Build Electronic Decision Maker Kit [An Electronic Aid For the Indecisive, Assuming They Are Decisive Enough to Purchase] or just shy of $7.

The blissful irony concerning this DIY Self Build Electronic Decision
Maker Kit is hard to escape as, seemingly aimed squarely at
electronically assisting the indecisive in decision making processes,
the target audience seems somewhat less than ideal, bearing in mind that
most will, arguably, not quite be able to come to a decision as to
whether to purchase this kit or not.

The device itself is provided in kit form, as the title would suggest,
and, once assembled, can be relied upon to make decisions on your behalf
at a touch of a button (assuming you make the decision to use the device
to help you decide what needs to be decided upon, of course - though you
could always have two, using the first to decide whether to use the
second, though perhaps you'd need three as'enough already).

The device, which is powered by a 9v battery, basically works by
flashing two LEDs, green for 'yes', red for 'no', with the speed by
which the LEDs are illuminated gradually decreasing until coming to a
halt - at which point your mind will be made up for you.

Great for those who simply cannot take responsibility for anything, the
DIY Self Build Electronic Decision Maker Kit retails for just shy of $7.
