Did the Oxtars not last Long? I have some on the way, the pro's for $140 to my door, seemed like a good deal. They will replace the ARC 220v i have been using for the last two years. If the bonded sole would stay bonded I would still run them. I have trie4d nearly every glue/heat gun/glue gun available. I have nearly lit the things on fire several times. For the price, $129, the 220v can't be beat, though all they have left are the 8s and 9s.
