I am partial to Northerns. I have one, Frank. They get bigger, have a really nice temperament, and lower humidity requirements than some others. They are also easier to find CBB.
Ask anything and I am happy to answer. The more space you can give, the better, as they will use it! They are quite active except in the winter when they usually brumate.
There is a debate about whether they need UV, but they do need relatively high temps - 95F +/- basking temps and I think they benefit from UVB and I give it and Frank basks often. They like to dig so substrate that allows this is good. Having said that, I use paper substrate but I ball up sheets he can dig in and provide several hides in different temperature zones.
They are very personable, learn who their keeper(s) are, and even beg for food.
Finally, diet should vary, but aim for 40% veggies, 10% fruit, and 50% protein. Frank will eat basically anything, but remember, they are scavengers, so food in a bowl works fine and it doesn't have to be live. Also, you will have to cut his/her nails periodically (not like a monitor - they are ground dwellers and in captivity often do not dig enough to wear them down - they don't need the nails long).
I am putting the link to Frank's thread below.

Again feel free to ask anything.
