Cheap keyboard just for composing/noodling?

[VREEEEVROOOOOW]

Any suggestion for a cheap keyboard just for composing/noodling around for melodies? I play guitar myself, but I always have "the whole symphony" in my head when noodling around. Now drums, I can just bang stuff. But for things like brass or other string instruments (or piano/keyboard even), it would be nice to have a small & simple keyboard laying around. Just something that sounds piano-ish. Basic recording/programming would be cool, but being dirt cheap would be cooler. Any suggestions?

Maybe a Yamaha Reface? They sound really good for the $

If that's too expensive, maybe an old Yamaha Portasound? They can sound surprisingly good with a little reverb and EQ. Not realistic, of course, but that's not always a bad thing.

Arturia sells pretty good controllers that come with really good sounding software, one of which is a grand piano sim.
You can pick a 49 key version up for just $150. I think they're only about 30" wide.

one of them casio "workstations" maybe also? they usually have a nice array of sounds from pianos to brass etc etc.
usually can be found pretty cheap too.
