Pros use heavy duty aluminum pans, which cost about $120 or less depending on size. Cheaper enameled steel (turkey pans) will do, but not as well. Big buck pans are no better than the heavy aluminum ones.
Whatever you do, do not buy a non-stick roasting pan. Non-stick is not needed and more importantly, it all but prevents the development of pan browning residue that you need to start a good pan sauce. See photo.
