Yes, I currently use a Makita BDF 440 - excellent machine and that LED has saved the day on more than one occasion. Just today I used it twice.
I like the size, feel and adaptability of the C12 - if only they came out with a Li-Ion version with LED I would get one instantly. The Li-Ion batteries on the Makita work like a charm and just knowing you can come back from a lengthy vacation, pick up the machine and know the battery has not drained flat is bliss. Oh, and they charge fast too!
Li-Ion batteries have been out for many years (in other applications, like mini car racing
) so the technology is well tested.
