The classic! This one has cosmetic issues--worn paint as can be seen in the photos. Does also have some sticky keys. They all work but a few of the upper keys are sticky sometimes. I have never looked into how to fix this because it never bothered me, but I will now and will update if i find anything. Otherwise works great. All buttons, sliders, mod wheel etc. Sounds awesome. Has a new battery. Comes with original manual, music stand, and a symphony 128 4 bank sound card. This does not have the stock DX7 sounds, but rather my favorites from the DX Rom series as well as some I've created. I have loved this bad boy and found its industrial, weathered look actually very charming. Selling because I have no space and need to get rid of something. Keep an eye out for more classic keyboards, I may list some others! thanks and feel free to message me with any questions.
