I'm afraid you won't get anything too good for the price.
I had more expensive Yamaha Arius, YDP 120 I believe. The sound was nicer than that of very cheap acoustic pianos like Samick or even cheap acoustic Yamahas, but then it heavily lacked breath and depth of an acoustic piano. Even pretty poor communist Calisia was very superior to that.
If I could get an old acoustic piano of even not too good brand, that had tolerable keyboard and could be tuned properly, I would always prefer the acoustic.
Not to mention the weighted keyboards in digital pianos tend to be terribly overweighted.
It is be ok for learning basics of the technique, you need weighted keyboard for that, but if you make good progress they're gonna take away your stamina away double quickly when you move to playing things like Bach's three voice inventions or fast tempo sonatinas. Even if your technique is correct, you can make all the ornaments with ease, and have no tension in hands
In Arius I solved this problem by cutting off half the weights from the keys with grinder. The keys were still heavier than in any acoustic piano I played on, and I played on like 20 different makes and models but at least I could finally reach the right tempos with the right technique (and I know what the right technique is, as one teacher taught me bad, I got injuries from that, then changed a teacher, found a guy who was very good at biomechanical aspect and we solved all the issues)
