Jim, You go around once in life get the Pa3x. Your audience will probably not know the difference, you will. There's something sonically different about the Pa3x versus the Pa800. I had no intention of buying one but due to some talk here I thought I'd take the ride to Frankieve's store just to see what it sounded like. I was surpsided at what I heard Layout of the controls on the Pa3x has been improved, it's built like a tank and it's form factor makes it simple to move.
Yea, the downside is the cost, I don't think you'll be disappointed.
