Russ,
The GW8 in my opinion isn't any better than the GW7. In fact, I think there are not as many sounds I like as much in the GW8 because the emphasis on the GW8 was for Latin music.
The new model Juno D "i" is the best sounding keyboard in a portable very light model. I've compared the Juno Di to the older Juno D and the sounds are so much better on the Di. The Di also includes a very nice mic preamp with reverb and echo, a vocoder mode and a USB drive port to playback standard midi files, wave files and MP3s. It weighs about 11 lbs. and can run on batteries as well as A/C. I have some customers who have come in and listened to the new i model and have been really impressed with the voices in this new model.
