I've had portable table saws and a radial arm saw. In the end I set up several tables/saw horses and do all my cuts with a 7 1/4" circular saw, a jigsaw and a router. Some day when my shop is bigger than my current setup I'll probably get an old full-size table saw but for now, this is the safest option for me. I can manipulate a circular saw much easier than a 4X8 sheet of plywood.
