Cass, I have a similiar problem.
My two active keyboards on the stands are Rolands top board, the E 80 and Yamaha top board when I bought it, the Tyros 2.
I will soon need to sell one or the other as We are once again going to be traveling full time in the motorhome.
I play one for a week and think wow, I will keep this one.
Then I play the other one for a week and think, No, this is the one I must keep.
This has been going on now for a year.
When I play the E 80 I play all big band music, boogie, Jazz, etc.
When I play the Ty2 I play mostly blues, and country.
I just can't decide on which one to keep or even if I could replace both of them with something else????
