Yamaha NP30 Portable Grand Digital Piano

Description
The new NP-30 Portable Grand delivers Yamaha digital piano sound and simplicity in a new lightweight, compact design like nothing else you've seen... all at a price point you won't believe.

Until now, there hasn't been an affordable 76-key keyboard that weighs ONLY 12 POUNDS and can RUN ON BATTERIES!

Keyboardists who don't need all the bells and whistles of sequencers and synthesizers will be delighted with this ultra-light keyboard. There are only a few sounds (a couple pianos, harpsichord, electric piano), but for little cocktail piano, wedding or singer-songwriter gigs, often you only need a piano sound. (Yamaha is known for its authentic piano sounds.)

No more breaking your back carrying your keyboard. Now if someone could just find a way to create a light and powerful amplifier... (This keyboard also has built-in speakers, but for most performing situations you would need more volume than they provide. However, if you're just playing at home the volume is sufficient.)

I did a lot of research before ordering this piano. Even so, I was very surprised at how much was included for this price. A WONDERFUL Yamaha digital piano with many fantastic features. The stand. The AC adapter. Even free lessons on music theory on a CD to get you started. Throw in all of the voices, sounds, songs, and ability to interface with a computer, and you have an unbelievable deal.
The only down side is that the software it comes with doesn't load on my Mac :-(, but since most things don't, I wouldn't downgrade it just for that. It interfaces with Garageband, which is the software I already use, so that's enough for me.
Oh, and talk about fun. I'm got this to practice my piano lessons at home, and the first day it came I had so much fun I went to bed with sore wrists. I kept trying out practicing my scales with different voices. I guess I'll have to "space out" my fun a little bit better in the future.
