Ok, so this thread has caused me to go and spend money, which is probably not the point of this board overall but there it is. When we first bought this townhouse a friend gave as a no longer needed string trimmer because I really wanted a patch of grass in our backyard and a full on lawnmower seemed excessive. (our backyard is roughly 25x25 and the patch of grass we put in is 6x10ish. I just really wanted at least a little bit of green) The free trimmer was 12 years old and came with 2 rechargeable NiMH batteries. The batteries didn't hold charge very well and although new non-OED lithium replacements were available chargers for the lithium replacements weren't. I wasn't comfortable with the idea of charging lithium batteries with chargers not designed for them so we gave the trimmer to Goodwill and bought a new Black & Decker trimmer. Since the new trimmer was awesome I followed up that purchase with a B&D drill that uses the same battery. Now I am in the middle of a couple of projects that require cutting a big piece of plywood into various pieces so today I looked and I can get a fairly small B&D circular saw that uses the same battery. I found a deal on amazon to get the saw, another drill, plus one battery, for $77, a really great price for all that. We don't specifically need the extra drill but it will definitely get used when we have projects that require both a drill and a screw driver at the same time since switching back and forth from a drill bit to a screw driver head takes a lot of time if done repeatedly. I suppose the argument can be made that spending money on a tool that will get used routinely and which saves me time is a reasonable part of simplifying my life...
