wow guys, sorry i ignited (no pun intended) such a debate!

good to hear all the differing viewpoints though.

i ended up buying this as above



i like the idea of just one battery....and the ability to adjust glow heat etc as required. the other good thing is, even if i decide i prefer a glow stick....i can use the panel to charge it at the field!

seems win-win, and a modest outlay anyway.
