Hi John, welcome.
You remind me of myself. I learned the piano at a young age and I stopped when I was around 15. Glad to hear your interest in music is back, I've been enjoying myself a lot playing music again. Bit cross with myself for not having done it sooner
But you didn't say what kind of budget we're talking about.
I've been researching into all kinds of different keyboards, as I have been on the lookout myself during the past couple of months. Not specifically digital pianos, but synths as well, as I also used to play synths a long time ago.
Personallly, I've become enamoured with Korg and so I may be a bit biased
So, my 2 cents, and some of my favourites which I have (briefly) played (there are lots of others, but I happen to like these very much) :
If you're on a budget, then I'd suggest the Korg D1, which has a really good weighted action. It's a stage piano, but ideal for the home. No built-in speakers, so you'll need a small amp or monitor speakers. Next up is the Korg Grandstage, also a stage piano, and almost four times the price of the D1, but it's such a wonderful thing to play (i.e. it speaks to me
). If you're into retro, take a look at the SV-1 (same great keybed, but it's quite old now, been out for ten years).
There's also the 'home pianos', like the B2 (with built-in speakers, and cheaper still than the D1) but that hasn't got the RH3 keybed of the others but I suppose it has the Natural Hammer action keybed of the Kross 2 88 and Krome EX 88, which is more than fine (to be honest, I'm more of a piano player than a synth player myself).
Also, there's the C1 Air and G1 Air, both more expensive than the D1, but more affordable than the flagship Grandstage 88.
If you'd like to add synth to your repertoire, I'd suggest a D1 (which only has 30 sounds) to which you can add a Kross 2 61 later on and connect them through MIDI. The combined price would still only be half of what the Grandstage 88 costs. Or, you can just add an iPad to the D1, with a small MIDI adapter and use Garageband for example, which would give you a whole new sound library right there.
On another note : the Casio Privia series are supposed to be very good as well, but they're not my favourites. Don't know that much about Yamaha or Roland (although, having owned an FA-08, I can confirm that the Ivory Feel keybed from Roland is very very good as well, so maybe the RD2000 might be something for you).
Kurzweil has the new SP6, affordable and supposedly very good. Not going into Nord territory, they're supposed to be the best, but have prices to match
Also take a look at the Kawai MP7SE. And finally, if you really want the feel of a real piano, with actual wooden keys (no plastic at all), try and have a play on the Kawai MP11SE, just a tad more expensive than the Korg Grandstage.
Most of all these also come with adamper/sustain pedal, music stand and in some cases, even a full stand (like the Grandstage 88), which is nice if you're a piano player.
I'm also getting back into music, and very excited about it. I suppose other people on the forum are more of an expert than I am, but I still wanted to offer some advice. Hope it helps.
