Sounds like the Journey is the ticket. I pretty much only use platy and recycled water bottles. I could treat in my pot then transfer, but not having to do this may be worth 1oz of weight.
Anyone seen any bargins on the Journey or Opti recently? I may post a WTB on Gear Swap, see if I get any nibbles. I saw a few Classics go up but I'm not interested in an 8oz gizmo, plus AA batteries can't last too long with that high output lamp. Anyway, I have a bung load of RCR123A LiFePo batteries for another toy I use.
