I'm slowly acquiring tools for working around my new home and I'm looking for recommendations for tools (power or otherwise) that I simply must have for indoor or outdoor maintenance. So far I have all the hammers, screwdrivers, levels, measuring tapes, and other small tools that I think I'll need, but I don't have many power tools. I have a power drill, a chainsaw, and hedge trimmers, but that's about it. What do I need next? A circular saw?
