I have a dewalt miter saw, and I love it. Overkill, but I bought it when I was doing trim carpentry. Cheap saws are not worth the savings.
I don't have a table saw, and don't have space for one in my tiny shop. I use sawhorses, a circular saw, and a straight piece of wood. I made my "rip stick" with a factory-edge from a piece of cabinet grade plywood (about 5" wide), screwed to a strip of masonite about a foot wide. The edge of the masonite shows where the blade edge is, so you line that up with the marks on the sheet you are going to cut, instead of measuring the width of the base of the saw every time. Saves a lot of hassle. I'll try to take a picture and post it after I drop the youngest off at preschool.
Actually, I do have a table saw of sorts, it's a jig for my circular saw. It's pretty scary to everyone but me.
You have to have a good, solid, flat work surface to get accurate and safe cuts in plywood. I use a pair of sawhorses and drop a pair (or more) of sacrificial 2x4's across it to make a good table. Remember, you want to support both sides of the cut to get a good line. If your workpiece or offcut are going to fall when the cut is complete, you're doing it the hard way.
I used to have a 4'x8' cutting table made ladder style with 2x2 with a set of folding table legs on the bottom. Worked it to death, and haven't had cause to rebuild it yet, but the openness of the minimal frame gives lots of places to put clamps.
My Golden Rule: Safety first, beer later, what's for lunch is third; quality is "job four."
