I'm soon to begin constructing a ground level (i.e. 14" above ground) cedar deck off the back of my house, and so right now I'm in the process of determining all that I will need to purchase before I begin, including a few new power tools. For example, the circular saw I have is okay for occasional use but I dread using it for a whole project, so I want to buy myself a considerably better one. Now, aside from value-per-price considerations, what should I look for in shopping for a very-good to high quality circular saw? And in particular, what should I make of "worm-drive" versus the more common, "side-winder", type saws?
A couple of acquaintances of mine praise their worm-drives as being inherently superior in every way to the ordinary (i.e. side-winder) type. But I've noticed that these worm-drive saws are comparatively heavier (which might not be ergonominally advantageous, I don't know). And the position of the handles on these saws just looks (to my minds eye, at least) to be awkward to handle and perhaps not intended for close, precision or finishing work.
Of course, since I haven't actually ever used a worm-drive saw, my untested perceptions of it don't necessarily mean a thing. Hence, I'm posting this message in the hopes someone might 'enlighten' me in this before I come to a decision what to buy. Thanks in advance...
