I love the feel of my yamaha motif keys es7. I was told by a yamaha employee that the keybed is used on several of their other models.
I don't know how serious you are about playing keys or what your style is but I like
water fall synth keys for everything except when using it to play piano. These type of keys
rule. When playing piano I prefer hammer weighted. Semi weighted is the worst of both worlds for me.
Also if you plan on doing any of the following:
1) laying down lots of base lines using your board
2) live gigging with it as your primary axe
3) classical piano playing
4) beyond beginners two handed playing
You will find the minimum of 76 keys much more useful. If your doing the any of the above, 95% time you need those extra lower notes. The extra notes up top not so much. It seems most of today's music doesn't often have to go below the bottom E.
My prior AXE had fewer than 76, and I would curse every time I'd start playing some new sheet music and then run out of keys on the bottom end.
