I bought a used 12 inch Delta brand miter saw a few years ago. It has been very good, but it has had some issues spring up the last few weeks. At times it doesn't cut all the way through (seems like it takes a few seconds to get to max rpm), and makes almost a grinding noise after I make the cut, bring the blade up and release the trigger. It tends to not stop right away after releasing the trigger. The brushes look good, but I wonder if it the trigger or brake mechanism that is starting to go. It is getting a bit scary to use and I would like to keep all my fingers. I am thinking of getting a new one if I can't resolve the issues. I would like to keep it under $400. I would like a 12 inch so I can keep my 12 inch Diablo blade. If anyone has any ideas and recommendations I would appreciate it.
