I'm very pleased with the part that I ordered from Arlington Power Equipment Inc. They had one of the lowest prices that I could find. They provided lots of feedback and I was able to track my order when they shipped it. I ordered an Echo Starter Kit on Saturday afternoon and it showed up on Thursday, so 4 business days. It fit perfectly and my chainsaw started up without any problems. It did not include the four allen-head screws to attach it to the chainsaw so make sure that you save the ones when you remove your old starter. It also did not come with the Echo logo, so I peeled the old one off and stuck it on the new one.
