field recorders & battery issues

["tempjez" tempjez]

I know, I know. This is a dull one for my first post here, but I just 
wanted to ask for thoughts on the following issue. I suspect this has 
been dealt with before though.

With something like the Sound devices field recorders (702, 722) they 
use Li-ion camcorder batteries & with technology moving so fast I 
wonder if there will come a time when it's just not possible to get 
hold of these. I'm suprised SD haven't thought of that. Does anyone 
know of alternative ways to power recorders like this, just in case ?

Also, does anyone UK based know of a good supplier for other mAh 
batteries & also CF cards. There are tons I know but it's always handy 
to know if someone knows a really good, reliable & resonable supplier.

Thanks.
