I've had an Echo CS-370 since 2008 and it still starts and runs perfectly to this day. Sometimes it wont get used but once a month or like this past month will get used several times a week. It's a pretty darn good saw for $280.
I've also purchased an Echo CS-400 $300 3 months ago and it is a fine saw and more powerful than the 370. I would have got another 370 but the dealer was out. I've been running this saw a lot lately and really like it.
I second M&L. Get into an entry level Echo or Husqvarna.
