Not used the pro version but you only use these when setting up and anything more than the axis keys is overkill in my book.

Looks as if they may be finishing with the express shuttle as a few people have got it on specials so makes sense to grab one now.

Mine came direct from Tormach, they have them screen printed for X, Y, Z, A and Step, still the same shuttle just a bit of a gimmick but theirs is still 80 odd dollars.
