The PA800 does not have a shoddy case or flimsy construction. It is well made and still maintains a reasonable weight. It also has great-sounding onboard speakers.
I wish it sounded a little better out-of-the-box, but the sounds are certainly in there.
As I recall, when the G70 was first released it didn't sound it's best. Roland later made a software upgrade that turned it around. The sound is unrelated to the weight.
And yes, if Roland made the G70 in a package about half the weight, I'd buy one. It does have its compromises, such as no multipads, clumsy fill/intro/ending operation, no style/lyrics display and a few others, but then none of the boards I've tried has been perfect.
I am 100 percent certain that if I take the time I can make the PA800 sound every bit as good as the G70, but the fact is I DON'T have the time to spare right now.
And, whether it meets with everybody's approval, I won't keep a keyboard that doesn't fit my purpose. The G70 came very close, but is too heavy. The PA800 is very close as well. The Tyros 2 was also an exceptional board, with no real drawbacks, but not exactly the distinctive sound for which I'm looking to find.
Having said all this, I will probably play the Midjay with controller for a while, to accommodate my comfort level and available time. When I get more free time, I may revisit the PA800.
Right now it's for sale.
