I paid $200 for a green, Japanese badged machine (White) but it had all the accessories and had a recent tune up (worth $100). However the main reason I paid that much was that it was the model my Mom had when I was growing up, and they didn't hit the market often so when one came up, I grabbed it with both hands.
I'm a sucker for a "cool" looking dashboard machine (one that has neat dials or lights or other stuff like that). It's so easy to fall in love with them so I've learned to be very, very particular and only fall if there was something truly unique about the machine.
