Am going to make some small boxes that I want to miter the ends. I would love to know what everyone thinks the best way to do that is?
I'd use a chop saw or a circular saw with the lines marked with a speed square.
If all else fails, you can go old-school and use a simple miter box.
Electric chop saw for sure
Not sure if this was part of the question but make sure you leave the cuts a bit longer than expected and cut them down to fit perfect. I always tend to cut things too short and have to get more wood.
Use a chop saw and some stops for the length .That way you don't have to worry about the pieces being a little off or cutting them long and creeping up on them.
If you're using a chop saw you're going to get a better job with a new blade that has more teeth for a finer cut.
Here's a couple more tips.http://www.woodworking.com/ww/Article/Cleaner-Cuts-with-a-Miter-Saw-7381.aspx
Small boxes just use your circular saw with the angle adjust with a ledge. Miter box is also good. Chop saw, not so much..
