Oh, the Yamaha Electone HC-2 is a pretty solid choice! For one in fine condition, you'd probably be looking at somewhere between $200 to $500, depending on the seller and any included extras. Definitely check for any electronic issues like sticky keys or malfunctioning buttons. Also, give a listen to all the presets and effects to ensure everything sounds as it should. Transporting it can be a bit of a hassle due to its size, so factor that into your decision if you're picking it up yourself. Good luck with your purchase!
