I checked with Greg Atwell from
www.brightguy.com and they can get the E1 for $56.95. It's not listed on the web site, but give them a call or send email.
I contacted
www.botach.com and apparently they didn't know about the E1 until I told them.
They said they'll be getting them in about a week or so.
I'm not sure how the E1 lamp assembly issue affects this information though.
As for batteries, both
www.brightguy.com and
www.uws.com offer the SureFire 12B for $35. It's essentially a plastic box filled with 12 Duracell Ultra DL123As for about $3 each. Duracells apparently work better than other brands (ie, Sanyo) because they can run longer before thermal shutdown.
Existing SureFire models are water resistant only. The new models like the D2, D3, M2, M3, M4, M6 (E1 as well?) are new designs that are truly waterproof and dive-capable.
Btw, I just got a PALite Survival Plus...and I have to admit that I'm pretty disappointed in the weakness and poor quality of the beam.
Also, 2 hours after I got it, the "strobe" mode no longer works. I hardly played with it!
Yeah, I'm spoiled by my SureFire 6P/P61.
