Avoid the chineesium copies. A friend bought one from HF that was a copy of one I have had for 30 years made by Snap-On. His would not work, always crooked no matter what we did, mine works fine and did the job after he gave up. Loose pivots and loose tolerances are death to a tool like that. Imperial-Eastman has several versions, they have been in business for a very long time and seem to make good stuff. You probably already know that you will need a DOUBLE flare tool, not single.
