I've currently got a Korg SV2 73 that I'm using as a midi controller. Needless to say, the built in tube doesn't do much to improve tone over midi 🤣. I'd like to sell it and buy something cheaper to replace it, and I'm looking for recommendations.

Here's my required feature list:
Midi out via 5 pin DIN, not just USB.
Weighted or hammer action.
Ideally 73-76 keys. I don't use all 88, and I like the compactness of 73.
Enough of a price difference that I can make a decent profit by selling my SV2.

I don't need any internal sounds, or any knobs or faders (I've got all those on my primary synth / midi controller). Just need a decent feeling keybed for piano parts.
