I'm pretty sure my parents paid $149 for the one they got me and my brother in 1994, was $229 at launch in 1993. Not sure if it dropped any more after that.
$149 + something less than $200, with the economies of scale of putting it into one system rather than separate systems, and it sounds to me that they maybe could have got the price down to $299.99. Interesting. Thanks for the information!
