I bought Skil's little 5 1/2" three years ago. I have NOT used my 7 1/4" since!  This feather weight lets you work all day long without fatique. I have so much more control with this saw, its a miracle.  A  couple of cautions though.  Its kind of hard to find replacement blades for  it.  B&D's Piranha blade is very good, if you can find one in the 5  1/2" size.  Also, its a left hand setup.  The motor hangs off to the  right.  If you rip using a nailed down 3/4" straight edge where the  motor rides above it (most righties do,) the maximum depth of cut is fairly  shallow (about 1")  Other than these two limitations, best buck and a  quarter I've ever spent on a woodworking tool.
