I actually bought the MT65 on the left new, back in 1983 and still have it. £150 in the UK back then. The only place selling Casios back then was a specialist organ shop, mainly full of £1000+ Yamahas. Trying the different Casios (probably those four) the tone on the MT65 was so good I thought someone had started playing a much more expensive organ behind me. When I realised it was the Casio there was no question as to which one I was going to buy despite it being the most expensive of the ones I tried. This guy does a preety good short demo
I don't think I have any from this line-up, I have several Casios but I think Yamaha was a little more popular over here, especially for the over $100 USD units. That guy does a great job in the video, I wish I could play better but they are still fun to mess around with.
