I like "Diablo" saw blades. They work well and last a pretty long time. For a general, all-purpose blade, go for what they refer to as a "combination". If you're cutting furniture grade wood, or thin stuff, or need a smooth edge, get a blade with more teeth. If you just want to rip through some 2X's, get a blade with fewer, but larger teeth. Larger teeth take bigger "bites" so they cut faster, but they also leave jagged edges (not an issue for stuff like framing). Smaller, more numerous teeth cut much slower (you don't want this if you're cutting a lot of framing or some 3/4" plywood, etc) but they also leave a smoother edge. Great if you're building cabinets or furniture. Now that you found your wrenches and can change blades easily, why not buy a set of 3 blades - one course, one combination, and one fine tooth? Then you'll be set for most general wood cutting you may want to do. ((For cutting anything other than wood, you'll need specialty blades, such as diamond grit. As at the place you purchase your blades))
