With regular handling and depending on the individual personality, a bluey could likely fit that description. Northerns, Easterns and Irian Jayas are usually recommended as a good beginner bluey. Westerns are hard to come by (don't know of anyone breeding any) and expensive (in the thousands). You'll have more luck finding an Eastern between the 2 species you mentioned.
