I agree about the price being too high
Original MSRP for a TG-16, one controller and the ever-popular (and RARE !)
Keith Courage, was $149 - I bought mine at that price in 1989 because I
wanted very badly to play BoxyBoy - (my memory may be faulty, and cause me
to exaggerate, but as I recall, between the time I spent playing the game,
and loaning it to friends, my per hour cost worked out to well under $1 !)
The irony is that two or three years later, when the skids were not only
under the system, but well greased, the official retail price was only
$29.95 - but by then, of course, it was too late
