Grace asked for a run-down of the saws we use on our renovations, and I don't mind talking about tools at all, so here you go.
Reciprocating Saw (Skil - $70)
We did a lot of demolition work on our house, so this saw has been worked pretty hard (I would estimate we've used up 30-40 saw blades). This type of work doesn't commonly get posts/pictures, but we used it to demo every single room, including the old kitchen cabinets and the back steps.
Jig Saw (Black & Decker - $70)
The jig saw comes in handy for tight/precise cuts, like cutting Mackenzie's name out in wood on her shelf, cutting holes for ductwork, creating the curved tread and riser, and installing hardwood floors (cutting pieces around vent holes, cutting pieces in corners and against cabinets).
Circular Saw (Black & Decker - $75)
I find the circular saw to be most useful for doing depth cuts, like cutting out the subfloor without cutting through the joists, cutting a clean line in existing hardwood, and cutting kerfs to make a curved riser. It is also good for making cuts that do not require the precision of a table saw and/or are too awkward for a table saw, such as installing subfloor.
Mitre Saw (Dewalt 10" - $250)
Most mitre saw cuts could actually be done with either a circular saw or table saw, but the mitre saw is much faster and more precise. Some of its many uses: framing (e.g. bathroom extension, kitchen), cutting metal furring strips for the living room ceiling, installing trim on the second floor, cutting and mitering pieces of MDF for wainscotting, installing trim/bullnose on the stairs, installing hardwood floors. If I had to do it again, I might spend the extra money on a 12" mitre saw, as the 10" blade only cuts pieces up to 6" in thickness, which can be a pain when cutting 2x8's and our baseboard trim (which is 7+" wide).
Table Saw (Craftsman - $?)
We have actually been borrowing this saw from Meredith's parents for the last year and a half (thank you Doug!). It is very useful for precise cuts (e.g. cutting wood for the built-in bench seat), for ripping pieces down to size (e.g. cutting down and squaring off doors/frames, cutting down window frames, cutting pieces of MDF for wainscotting, cutting shim pieces to prepare for drywall), and for ripping pieces to the appropriate width (e.g. ripping down hardwood floor to meet height of kitchen tile).
