I won't. I have traded, bought and sold SEVEN arrangers this year, and I'm actually ahead a little. Well, three of them were PA4Xs, and there was an SD7, two PSR S970s, a PA4X, an EA7, a Korg Microarranger. . . Wait that's nine. And I feel like every deal was fair for both sides. That doesn't count the BK9 and EA7 that I sent back.
I really tried to make every one of the work for me, but so far the PA4X rules the roost.
They are tools, not family members!
