Your favorite keybed in a synth?

Looking to invest in a high end polysynth so I dont have to fire up the computer every time I feel like practicing sound design. My favorite keys by far are the motif xf6 keys but I want a dedicated va synth not a rompler. The problem is my local guitar center doesn't have any on display to try out. My first choice in terms of features was the prophet 12 but I happened to come across a used p8 the other day and was surprised at how lifeless the keys felt to me. Choosing a set of keys in terms of feel is a shot in the dark for me. Those of you who's hands have been around, if I like the xf6 keys what hardware would you reccomend? I'll compromise on anything else but that...
