I am looking to add a miter saw to my shop. But I've never used one, and know very little about them. In looking at saws and trying to compare features, it's very confusing. Some are single bevel, double bevel, compound, sliding... what do all these terms mean? Which features would really be useful? And how much should I have to pay to get a decent saw? I know that I would like to have one with a laser, but beyond that...

Someone please help! I know you guys will.
