Trey,
What I think everyone is trying to say is that these multi purpose machines can get the job done, and some people have made superb items with them.
But like all sorts of multi purpose machines or items, they will never match the versatility and rigidity of having separate dedicated machines, as everything is a compromise to get them to work together in one package.
Another issue is if you find the lathe is OK for size, but the mill is too small for what you want to do, you will end up buying a larger mill in the end, so making half your purchase redundant.
As mentioned earlier, for certain people and situations they are perfectly acceptable, and maybe in your case that might be true, but for the other 90%+, they just would not be considered.
The lads on here I am sure would support you in whatever choice you went with, but please listen to all responses before making your own decision. I am sure the all in one lads will pop up eventually to tell you their thoughts.
