If you’re going to be transporting your unit regularly, you should aim to keep weight to a minimum. Look for something lightweight, with convenient carrying handles, or a stand that can be wheeled around dolly-style at the worksite. Conversely, if you’re only going to be using your portable saw occasionally, you can probably stand a bit more weight.
The machine has a more conventional rip fence/rail arrangement. The right half of the rail assembly folds out so the saw can achieve its full 30″ of rip capacity — wider than any other model here — but the fence would not slide smoothly over the rails without catching on the hinge joint. While the rip fence did maintain its locked settings, it lacks the heft and build quality of the competition.
