That question is a bit of a double edged sword.
You first need to shop around for price, I think you can find a better price elsewhere

I wouldn't pay $3899 for a T3 even if I won a mega millions jackpot. That's not because I don't like the Tyros3, I do. If the price is in line with what I'm willing to pay and I was able to sell other equipment to help finance it I would. But to answer your original question if I had to dig into my pocket and come up with $3899 good or bad economy I would not.
