At $150-300, you probably can only find a 61-key unweighted keyboard. While it wouldn't be as good as a digital piano, it can be used to learn the basics or if you do not have intention to play classical piano or play on a real piano eventually. Most keyboards, even at this price range, should have headphone and USB ports (for MIDI). Within this price range, the Yamaha PSR-E373 and Casio CT-S1 are probably the best options.

Starter keyboards will almost always invariably sound bad, especially the non-essential sounds (if piano and electric pianos are the main sounds, then strings and organs would be the non-essential sounds). Even higher on the price range, keyboard strings don’t sound like real strings. You gotta go for something like a $4,000+ Korg Kronos to have good string sounds. If anything, I’d suggest you look into buying a cheap midi keyboard (like M-Audio or something), then buy a strings plug-in and use it on your computer. More on reddit.com
