Makita is the way to go IMHO.
I have sold them for 18 + years, and rarely have a problem.
The 12 volt batteries (redtop) had some issues a few years ago, but they extended the warranty to us dealers so we could replace the batteries 3+ years from the sale date.
Unfortunately the old style (NI/NIH) batteries did have a significant price hike. On the other hand, the new LI tools are much lighter, and seem to hold up as well as the old school stuff.
The last time I sold a non LI Makita ( probably a 9.6 pod drill/flashlight) was at least 5+ years ago.
The new small format (pocket driver) 12 volt drill has the same power as the full size old style 9.6, although with a shorter run time-but a faster charging time.
I replaced my 12 year old well used 9.6 (batteries were fading) with this, and use the 18 volt only for the really big stuff. In fact I use the 18 volt flashlight more then the drill.
Now they have extended the LI to 3 years across the board, including the batteries.
Haven't seen any over charging issues.
In the last year I sold 50+ of the 18 volt combi kits, that included a free tool (like the OP driver-or a grinder rep saw/vac/blower or radio). The radio by the way sounds very good.
So far I had one 3.0 ah LI battery go bad and that's it.
Makita started out as a electric motor manufacturer, and is still probably the only electric tool manufacturer that actually makes it's own motors. They seem to get the same power as the competition, with a slightly smaller/lighter format-that still hold up well over the years.
I bought my first 7.2 stick drill in 1987-metal box-1 battery-no flashlight for $249.95. It still works, (5 mn run time now) and a bit noisy, but I used it from everything to drilling out exhaust manifolds, to building several decks/home improvement etc. It got loaned out a lot as well. Awkward and bulky now compared to the new units-but those drill were legends.
Good stuff!:thmbsp:
