Guitpic1.........Try before you buy is the best advice no doubt it.
I had no desire to purchase a Pa3x it was on the market for about a year, then I tried one and decided it was for me. As much as I love my Tyros5-76 seems most gigs I use the Pa3x in my opinion it's a dream for live play and that's not to say the Tyros5 is not great to use for live play, right now I prefer the Pa3x. Pa4x in my future.....maybe.
Great to read about your work with photography. I'm a Canon shooter and have a small collection of lenses with a couple of L series. At this point the big question was should I move from DSLR to mirrorless? I just picked up a Fuji Xt-10 mirrorless haven't shot with it enough to make a call. But I like it's smaller size for street shooting.
