In the Ely area, I've used Canadian Border Outfitters (CBO) a number of times when I first started.  They have a very nice arrangement.  Meals in the cook shack are good and have stayed mostly in the motel-style rooms rather than their bunkhouse.  They are located on Moose Lake and provide tow service (even as far as Lincoln Island).  They have changed hands a couple of times, but have always provided excellent service.

If headed to the west side (Crane Lake), I've used Anderson's mostly (but Zups is also great).  Anderson's also has housing by using the "motel" across the street.  There is also lodging at Crane Lake proper.  There are various places at Crane Lake to have meals, but Anderson's itself does not do that.

On the east side (Saganaga Lake), I've used Voyageur Canoe Outfitters.  I didn't get to take full advantages of their services since we were delayed in our arrival ... they only got to provide tow services.    They did what was asked, but didn't seem very attentive (probably because they had already seen all of their other customers off for the day).

That's what I know for south side outfitters.
