If you want a keyboard, you can pick up an old 90s rompler for around that price. Love the keybed and build quality on my alesis qs6, but I just use it as a midi controller. If you just want knobs and sliders, look at something like a used notation launch control xl. If you want a full midi controller with keys, knobs, sliders, pads, maybe mpk mini? Nothing modern will have nice keys in that price range, though. Plug in to your phone/iPad/laptop, download synth one or surge xl, spend some time mapping and away you go. $100 is not a reasonable price point for good hardware that actually makes its own sounds, but who needs it when you have a super computer in your pocket.
