My Comments
After regretting selling my HP-800 I have looked for a replacement. I had almost bought a RD-300, but it sold before I could get it. Then in my local buy and sell I found this and a little sound module (em-101) for 50$ so I bought it. It weighs almost 200 lbs, but luckily it comes apart. There is one sticky key that I hope to fix (e5) so I don't have the same thing happen again. The guy couldn't find the power cord so I bought it without hearing it, and now I have to buy yet another power cord. When I got it home I was a bit disappointed. Maybe the HP-800 sounded better, or maybe I just remembered it that way but the sound just barely passes for a piano sound. The keys do play nice though, and I do like the electric piano sounds. The tremolo is very cool, it has a speed control and chorus. It can be programmed to any MIDI channel (doesn't remember it though), has an audio in (in stereo), a brightness control, volume, soft and damper pedals, and a really heavy stand that has at least 4 speakers, is 30watts a side and is really really heavy. When I got it set up I played it till my fingers hurt. So even with it's shortcomings sound-wise it sounds close and is alot of fun to play. If I were pressed to take this to play live (I certainly wouldn't be carrying it though) I don't think too many people would complain that it doesn't sound piano-like enough. I'm not entirely sure but I may not have found my keeper piano, but this will certainly do for now.
I rate it

2018: Because it literally has it's own sound system it is near but not in the keyboard set-up. I have the EM-101 running through it as well for now.
