[Dewalt Battery Update]

Does DeWalt make a 14.4 v Li-Ion battery?  I'm looking for a 14.4 v drill, but so far all I see are Ni-Cads.  I am a weekend DIY'er.  I may use the drill a few times a month.  Will Ni-Cads suffice for me?  When I hear the name Ni-Cad, I think of my old camcorder battery, and having to discharge it fully before recharging (because of the memory effect) and then not having enough battery left when I needed it because it was partially discharged before I started using it.  I think you know what I mean.  I just don't want the hassle of having to worry about how much charge is left in the battery.

I will have to shop around, but does anybody have an opinion as to whether to 18V drills are much heavier than the 14.4?

[Rohm vs Jacobson Chuck]

Does anybody know which chuck the DeWalt DCD930 has?  It's advertised as a self-tightening chuck, but I can't find any more on it.  Thanks.
