Donny,
I was in a similar situation up to about 2 months ago. I had been playing social clubs frequented by mainly mature people. I played as one half of a duo, a singer/bandleader and myself on keyboards. The guy I played with (he hired me)did all the singing and would not allow me a chance to do some singing.He sang very old school whereas I would be be singing more up to date stuff. We were getting regular work and earning enough money for the past 7 to 8 years. I eventually could take no more, the music was dreadfully stale and predictable, my playing began to disimprove. I eventually "pulled the plug" I could take no more. I now feel a free man and other musicians are starting to ring for stand in work. My plan is to become a OMB doing the music that like at venues that I like.I want to play with other musicians.
Donny, you need a change but not another new keyboard. Seek out new music avenues, move around other musicians and try new ventures.

Good luck Donny
