Methinks you want a PSR because it is one you could actually carry to a gig, and not having a car, that would be beneficial.
That "canned muzak sound", or "smooth and detailed", as I like to call it, worked great for those lucrative restaurant gigs...no fighting off drunks...and a nice meal at the end of the gig...those jobs helped me pay for a house, car, groceries, utilities.
As others will tell you, the Yamaha sound works very well for other type gigs.
I did a season of theater concerts alternating between a Tyros and a PSR-S series, pumped through two Bose L1's in beautiful, sumptuous stereo...nothing but compliments on the sound.
It also says a lot, as well, at how nice the Bose and Yamaha work together.
The Audya, although issue free to a few owners, is unbalanced, buggy, and fraught with problems...much like a bad marriage.
It's good to see they have a marriage counselor in the guise of AJ...they'd be in divorce court a lot without him.
