Hi CNS,
I put off getting a digital piano for ages as they never have same sound as an acoustic. However they are undeniably much more practical! So now I've got both, caused a bit of friction at home by taking up too much space in the living room, my husband naively thought I'd sell my 'real' piano having got the digital one. My suggestion of getting rid of the telly to make more space was rejected.
Anyway, the best thing in my price bracket was a Kawai ES1, it does have weighted keys, and came with pedal, you can plug in your headphones, play through amp etc. It doesn't have too many fancy sounds, but that's no issue as I'm not interested in sounding like a digital tuba, and it had the best piano sound out of all the ones I tried. The more buttons, the less authentic the actual piano sound.
However no digital piano will ever be as responsive as an acoustic one. It also has the facility to record 2-3 min snippets and play back which is useful when messing around with chord structures etc.
In defence of digital pianos, if you're playing with other people you can control the sound/volume and in this respect they are better than acoustic.
Hope you find something you like.
