Well Donny, the 3k had at least one feature the Tyros1 didn't have, that being the "USB to device" port, which turned out to be a deciding factor in my purchase.
I'm very happy with the 3k...light, does exactly what I need, easy setup/tear down and the right price for my budget.
If the PSR-S900 just has SA voices, and two "USB to device" like the T2, I'll be more than happy, and will probably buy one.
