A Casio VL-10 on eBay, and at the time of writing, going for over £20. The VL-10 was smaller than the original VL-1, being only 8″ long. Ok, it only had 3 voices, and a 100 note sequencer, but for 80’s that wasn’t too bad.
Imagine what you could get packed into a box that size now! If someone was to design and manufacture something like this now I bet it would be awesome!
