Stay away from M-Audio. The newer Akais aren't very good either. Try Nektar.
It all depends on how well you already know the keyboard though. A cheap Akai LPK25 is good enough for absolute beginners. But if you have some piano playing experience, I would go for something like an Alesis VI49
Not op, but the alesis V ones have such a comfy key weighting and are quite cheap. Only thing I don’t like is the drumpad on the left feels cheaply made
