Donny, I can't imagine you without a keyboard in your house ...
... It would be like a car without tires - it ain't goin' nowhere!!!
Forget about the latest and greatest, or the 'panacea' - the be all and end all' - and just get yourself a keyboard to PLAY WITH !!! ... try crazy stuff like playing rock tunes as a bossa or a bossa as a polka ... just screw around and have FUN !!! ...
Then, when the next lightening bolt strikes, go out and get what you think you need and just have fun with that ...
You may never find what KB makes you truly happy, but it could be a lot of fun searching for it ...
