I own seven tools [trim-saw, jig-saw, drill/driver, recip' saw ("saws-all"), florescent light, hand-vac, hammer/drill] in this 19.2V series, and really like them. I can't compare these to other brands, nor can I speak to how they'd function under commercial (daily/heavy) use, but for an occasionally serious weekend-warrior, they've held up very well and have done everything I've expected and more, whether re-decking a porch, tearing down an old metal shed, building a shed, sheet-rocking, etc. With three fully charged batteries, you can do a lot of damage before you've run out of power, and the charger restores them quickly.
Sears packages these 19.2V tools in different combinations; I think each combo' is on sale at some point over the year. I'm unsure this is the package I'd first buy only because I have little faith in the orbital sander -- in -any- orbital sander for that matter, as even corded ones take forever to do not-much.
Note: these tools aren't light, individually and collectively. My first package (the first five I listed) came in a large "suitcase" which was heavy and bulky; a yet-larger collection comes in a rolling trunk (like a wheeled ice-chest). Neither is fun to tote about, carry up from the basement, or put into a car. Further, to some extent these are "toys for real men" -- meaning that not many women would care to hold these tools in awkward positions for very long (say, sheet-rocking a ceiling) as the powerful battery-packs make these tools a bit heavy.
Sears keeps adding new tools to the line-up; these aren't necessarily cheap, but they can be interesting: if the project arises, I'll consider that 90-degree drill [say. for working in cabinets or in confined joist or stud situations]; and I keep looking for an excuse to own a spiral saw.
Anyway, that's my experience with the line-up. Take care out there!
