Tim,

What wasn't cost effective was rigging up a cassette player's reading 
heads to read the right channel of side B while playing side A to 
play back tracks 3 and 4.  If it had been just a matter of speed 
control and switching left or right channel, it would've been 
trivial equipment modification.  As it was, you had $20 walkmans 
being sold for upwards of $150 because of the complexities of the 
modification.

Once you have the special equipment needed, I agree that the cost in 
its day was dirt cheap.
