Not sure why you'd be against a large crate that has a divider. They work very nice and "grow" with your puppy as they grow.
And how many times do you think you'll be moving the crate? Usually you want the crate setup where it's going to be permanently so the dog gets use to it's new home. Some will say to start out in your bedroom, then put it where the crate will be permanently but personally I don't agree with that method. You start the dog where the dog is going to stay. And it's not a place of punishment or "time-out", its to be used as a safe place to keep your puppy/dog when they can't be supervised. In time the dog will look at the crate as his/her den.
Not sure if that helps but thats where I stand... and CONGRATS on the new puppy and remember... photos or it didn't happen.
