Recent talk about moving from the Ryobi Ni-Cads had me check out Home
Depot.

They are running a couple of specials pre-Father's Day.

1st deal: $99 combo which includes 2 18v 1.3AH Li-Ion batteries, dual
chemistry charger (Li-Ion and Ni-Cad) and two tools, your choice of

A, 1/2" drill and 1/4" impact driver

B. Reciprocating saw and 3/8" drill

C. Circular saw and 3/8" drill

I really only wanted the batteries and charger but figured by the time I
spent $130 for the big batteries and standalone charger, I might just as
well grab two tools and two of the smaller batteries for an additional
$70. Now we have a nice cordless reciprocating saw that either of us
can use for yard work, etc. Seems fairly sturdy so..

Finally, they have their BEST Li-Ion battery, the 4.0AH beast on sale in
a special 2 for 1 pack which also sells for $99 or half price on the
individual batteries.

If you have the original blue Ryobi tools and are looking to upgrade
your power supply, now's the time to jump. I've never had a complaint
with the tools themselves but the NiCad packs, being NiCads, are a ****
poor PITA
