I would not overthink it too much, but rather jump in at a comfortable financial level. Then try to figure out whether this whole vinyl thing is agreeing with you, and learn what you like/dislike about that platform. Without a reference point, it is difficult to find a direction.
I would think more about functionality than sound. For instance with the Mofi you need to move belt for 33/45 speed change, whereas the Pro-ject has button. Do you have significant holdings in both 33s and 45s? Is that an issue for you?
At that level, there is one more important factor, the phono stage. I would consider PS equally important as cartridge. I would think that with any >1K TT an external PS is step up over a built-in from "normal" integrated amps/pre-amps.
