Update:
I went to play the Juno-G and decided to buy one. The fact that it was on sale definately was a factor also. Most of the sounds are pretty good and very usable for my needs. No, they don't sound quite as good as a new Motif or the new Fantom, I can't complain for the price. The pianos are decent; a bit dark but still good. Very good synth basses(no surprise from Roland) The organs suck unfortunately. The strings, rhodes, synths, and pads are nice. This thing also has a sequencer, sampler and audio recorder. The graphic interface is really nice also. You can see the screen from a mile away.
In short, this is a great value especially for a gigging musician that wants a lot of sounds in a light compact keyboard that has many features that get left out when you spend under $1000.
