I saw it on my way into town, somebody put out a casio WK-3000 piano out on the curb for free, with the stand power cord and even manual. The craziest part is its fully functional. Not a darn thing wrong with it 'cept some dust. Now I have to learn piano.

Maybe old ones (I guess like Ops)?
I’ve got a CT-S1 as a portable I can chuck in the car & love that thing, it sounds awesome too, sometimes more so than my ‘proper’ weighted Yamaha keys…
Also, Yamaha easily has the best sampled piano sounds out there for consumer grade synthesizers. Maybe that’s changed in the past 6 years or so, but I haven’t been able to find a comparable piano in any VSTs or onboard synthesizers. It’s a shame they can’t seem to make percussion instruments at any realistic rate… have had to switch my ensembles to inferior products because Yamaha’s lead times are fuckin 2-3 years. Unbelievable.
Yeah, their higher grade stuff is fine. They corner a lot of the beginner market, which focuses on affordability and function over sound quality, so I sort of have that opinion of them. They are a legit company with good products at the higher end. Heavy hitters during the rise of synthesizer in the 60’s and 70’s.
