[NTLK] AA NiMH Rechargeables

[Bradley Loeding]

There are on-line outfits currently selling them for $10 - $12 for a
pack of four. Expensive... but with a claimed charge/recharge cycle of
1000 times, it should be worth it. Word on the street is that Sanyo is
coming out with "real" C & D size Eneloops sometime this year.
