I have played a few of the boards you mention, and all would bring you enjoyment. But, for support, info and fellow users on line, I would go with one of the Yamahas.

Since weight is not an issue, the 76 key PSR 9000 Pro would mostly likely be my choice. But, keep in mind, it does not have internal speakers. The PSR 9000 has internal speakers but only 61 keys. Both offer great sounds, great styles, are versatile and built to last.

The PSR 2000 is my choice for gigging, mostly because of its great sound, unique operating system and light weight. The construction is not as solid. But, overall, it is a GREAT keyboard.

The Tyros is getting excellent reviews... and if I were starting from scratch it would be in the mix. But, I would have to get my hands on one before I made the commitment.

Good luck. This is the place to get the straight scoop from avid users of all kinds of keyboards.
