Casio Privia. I've had my PX-150 for 11 years. 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

if you can't raise your budget you're going to have to settle for an extremely low quality instrument. More on reddit.com

The best keyboard to start with is an 88 key fully weighted and graded keyboard as that covers all the bases; the full range and real feeling. This helps with technique and finger strength and dynamics and all that good stuff because it is mimicking a real piano. A good starter keyboard is something like the yamaha p-145 or p-225 personally I have a roland fp-30x and I think it has a much better action and feel than the yamahas, so you could also check out the roland fp-10x. Some other well known names are Kawai and Casio but I dont have any personal experience with them so I cant give much advice on them. Look out for Yamaha and Roland, these are pretty much the best of the best. However lets not kid ourselves these all still cost a fair bit of money, so if you dont want to spend this much then you can find some keyboard that have touch sensitive keys as you can still somewhat get a feel for dynamics (but this is nowhere near the same level as with a fully weighted keyboard) It also depends on what youd like to play, if you just want to play some of your favorite pop songs and play around with different voices then id recommend something like the yamaha psr e373. If you want to get into classical or jazz or want to really become a good pianist then id strongly recommend getting a good keyboard from the get go. The best advice I can give you is to go into some music stores and try things out, this is CRUCIAL! maybe you will watch videos or read reviews but you really cant know for sure unless you go in person and try it out. Sorry for the essay, but TL;DR is: Go to a music shop in person and try out their instruments. More on reddit.com
