A year ago I had a spring fail in my old/cheap system with tension springs. I was surprised to see the level of scamminess present in this particular area of repair. After seeing that a set of replacement springs from a big box store was under $100 and wouldn't be that hard to do myself, I figured that it would be reasonable to pay an extra $100-200 just to have it done while I was busy with other things. One guy over the phone tried to convince me that he would need to replace the entire cable system as well and lost any interest after I told him the cables were fine and the spring had failed from fatigue in the hook section where the cable was attached. Someone else was "dispatched" from a local-sounding number and showed up with out-of-state license plates on his van. He quoted me $800 for the repair. I tried not to be a jerk and told him thanks, but I'll be looking around some more. He then dropped the price to $400, saying he'd do the job for that if he could replace only one spring. After another thanks, but no thanks he became aggressive and said that was a special one-time price that ended when he left my driveway. He later texted me with a $200 dollar price, but by then I had already arranged for someone to do a full conversion to a torsion system for about $500.
