I'm afraid that the power miter box is the only tool that will give you consistantly accurate miter cuts, with a good carbide 40 (or more) tooth blade. The first 10 years of my miter cutting were done with a combination of table saw, manual miter box's and by hand....which is how my dad and his dad before him used to do it. It took much patience and many bad cuts before consistant good cuts were possible. But unless you have the time, patience and money for scrap to learn this, the power miter is the way to go. I have had a Delta 10" compound miter box saw for about 8 years now and it has been an incredible tool for me. I can't imagine life (at least my construction life) without it! Also, DeWalt and Mikita make good saws. You can get a 10" Delta compound saw from HD now for about $180 or so ..... trust me...its worth it.
