thanks for the input, I ordered some cartridges from Smoke51 (it may have been my connection/browser/laptop but the shipping charges/PP total didn't show up until i got my email receipt...turned out to be a bit pricey for a single pack...oh well)
but I then decided to order a VaporKing from vapor4life, as my S/O is now dedicated to vaping and no longer wants to share her WhiteCloud kit

about half the price of what she paid.
regardless, if this gets us of analogs, the savings...well, you know.
as to the battery issue...WC is not the only one listing those types, and I have had endless number of Li-Ion batteries(the ones that had the massive recalls) for my cell-phones, while some pretty badly abused Nokia ones started to bulge, I never had one blow up. If it is a bad charger or crappy construction, any energy storage device will fail with relative outcome.
Lithium Polymer batteries have been around since the '90s, while they have different risks, they are often preferred in RC and airsoft gun application, which, while not truly exposed, have to handle more stress then an e-cig.
from wikipedia:
Li-poly batteries are also gaining ground in PDAs and laptop computers, such as Apple's MacBook, MacBook Pro, and Macbook Air, Amazon's Kindle, Lenovo's Thinkpad X300 and Ultrabay Batteries, the OQO series of palmtops, the HP Mini and Dell products featuring D-bay batteries. They can be found in small digital music devices such as iPods and other MP3 players as well as gaming equipment like Sony's Playstation 3 wireless controllers[2]. They are desirable in applications where small form factors and energy density outweigh cost considerations.
I think if you handle any battery(LiPoly or LiIon) with the deserved caution and not do stupid things that show up on youtube, overcharging a damaged battery or applying the incorrect voltage, you are pretty safe. Statistically, it can't be any more dangerous then analogs.
