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. More on reddit.com

Yamaha is definitely a safe bet for a first digital piano. I've been using the clavinova clp-525 for about 5 years and it's great. Yamaha digital pianos in general feel very much like the real thing, and maybe better in some ways as they never go out of tune Edit: im prettu sure they all do midi input as well so thats another plus More on reddit.com

Just bought a PX560 from Casio, and are amazed at what it can do. It has a lot of Piano tones, 88 weighted keys, and a full Synth workstation with recording abilities. It first came out in 2015 and is still ahead of it's time. Bought it cheap, lightly used, as few people can figure the thing out, as it is a complex beast. It has nice built in speakers, and a full set of connections for stage use. Definitely a Pro quality Keyboard, that can stay with you a long time, and something you can grow into. More on reddit.com
