OK, downloaded and installed, despite terrible directions with obvious cut and paste errors ... If anyone else (esp. B-Man) does this, feel free to ask for help. I've tested it a bit, so far so good, but will spend more time with it this evening before I comment much.
@Bellyman Ha, I know how you feel. I've had the RD-2000 for maybe 3 years now, and I love it, but it's never left the house. That's about to change! I started teaching a pal to play guitar this year and we have a little trio (him on guitar and most lead vocals, my wife on drums, me on bass or keys) and we're ready to start performing for people, which will really be the first time I've played piano in a live setting (lots of experience in bands on bass but piano has been limited to recording videos). In a couple of weeks we're having a garage party at my house and will provide some live music, then a similar thing at his house over the Labor Day weekend. We'll see how he comes along on guitar, but we might even play real venues at some point!
Anyway, I'm already having the same thoughts. I love the RD-2000 but it's almost 50 pounds! I have a wheel case for it, so that will help some, but I'm still tempted to get something much, much lighter. I'm starting to think that portability might outweigh compromises for action and sound, especially since I'll be playing in a group rather than solo.
The Kawai ES920 is definitely one I've looked at. I suspect the action will be adequate, especially after I get used to it, but there aren't any for sale in my area, so I'm going to have to wait until I travel a bit further to try one out. It's 38 pounds, so a bit more than ten pounds lighter than the RD, which I guess is significant but maybe not enough to make it worth the change.
It does occur to me that a lighter action might be a bonus for longer gigs, and that any clicking and clacking (like my older Casios used to do) wouldn't be heard over the sound of the band anyway. To that end, I'd like to check out a Kawai ES120, and maybe even some of the newer Casios. I know about the latter's short pivot, but we're playing pretty simple rock and blues stuff right now that is very white-key friendly and doesn't require a ton of playing up by the fallboard. The Casio CDP-S360 is only 24 pounds, so that should probably be on my list.
I've also wondered about giving up a weighted keyboard altogether as long as the action feels otherwise substantial. My Roland VR-730 is semi-weighted but really doesn't feel piano-like at all (it's more for organ-style and synth playing). Maybe I should just suck it up and learn to play the piano tunes on it, since I'm already using it for a couple of other songs for organ and EP sounds. Otherwise, I've heard good things about the Roland GO pianos and keyboards, so I might see about testing one of them out.
So yeah. That's all by way of saying: I don't have any good advice! 😃 I'm definitely in the same boat. I'll keep you posted if I end up going with something else, and you do the same, please!
