For that budget I don't think you could get a reliable new 88- key digital piano. I've never bought a used digital piano, but most people on this sub recommend looking into the second-hand market, as you may find some Casios, Yamahas, Roland, and other used 88-key fully-weighted digital pianos brands for around $300 (sometimes a little bit more, depending on the level of usage of the digital piano). That being said, I recommend you get a new Casio CT-S1. Which you can get on Amazon for around US $270. Check for all the different offers and stores you can, so you'll get the best deal possible. The CT-S1 features 61 light weighted keys (still they feel a little bit like semi-weighted, I believe) with touch sensitivity, which is crucial for advancing as a beginner. All the other features are cool, but the most important thing is that it has a "recent" sound card which sounds very good for its price. Perhaps it's major disadvantage is that it doesn't feature an LCD panel for the controls (unlike my CT-S300 lmao), you have to check for command combinations on the user guide to change the settings. I know this because I own a Casio CT-S-300, which you could say is an older version of the CT-S1. I got it for $200, and to be honest I couldn't be happier with it (considering its price range). So if you tell me you can get an improved and updated version of the CT-S300, for $270 I'd say go for it. Of course I'd recommend you go to the store and check and play-test any keyboard or digital piano before you buy it. Also always ask for the warranty and the refund policy. It will save you a lot of possible headaches. Answer from NoDragon3009 on reddit.com
