Not trying to control you, but there are better options on cheap glass, for example
http://www.pipesdaddy.com/product-p/vp-0022.htm (Its a favorite with a lot of us on FC),
but here is a good thread over Cheap, high-quality glass (if you haven't checked it out) http://fuckcombustion.com/threads/cheap-high-quality-bubbler.5255/
I don't know when you are planning on buying a vape but I wouldn't consider the HI if you aren't okay with waiting MONTHS, primarily because you don't have another vape to tide you over during the long wait.
I understand the solo is portable but in my opinion all these devices do one thing in common and the Solo definitely does it, along with TASTE. (So say the Solo users)
Take being portable as a benefit, isn't their also a power adapter for it? Or did I hallucinate some cool shit?
EDIT:
Darn Vorrange, you must beat me at every post. Need to step up my game.
EDIT 2:
I would also take in customer service, warranties, and reliability in to consideration.
Logs from what I have read and seen from mine (which is NEVER off) are pretty reliable and easily fixed.
ahah, no harm intended. Solo is great too, love mine. My WW never failed me and it has survived its fair share of hits and bumps. Plus, its small size make it ideal to transport, taking as much space as my solo in my backpack. If you want something that you can carry around but no need to have batteries, then a log is a no brainer.
If the portability could be useful, the Solo is a likely possibility as well.
