I think your best bet is to get one from Frank. I'm sure he has a return policy. My bet is that once you try the T4 you will be hooked and enjoy using it with your recordings far beyond any enjoyment you have had so far which is what it's all about, isn't it?

Nobody can really tell you which choice to make because they all use their own reasons and rationalizations.

Rationalizations is what keeps a lot of people from having what they really want.

I've never been thrilled about the extra money I had to spend to get a Tyros over a PSR (as nice as the PSR's are BTW). But, having played both, was it worth the extra money? You bet. No real comparision IF you're really making use of all the great sounds.
