Vision Spinner is great, I have the 1300 mah, they sell for about $25 online. The joyetech Ego C Twist is pretty good too, actually the Spinner and Twist do the exact same thing, and both are built well. I know you said money tight, I can relate, either one of the two device I mentioned are really good ideas just to keep in mind. Both of these devices should be able to use the charger you already have for your Georgie.
The biggest difference between the Spinner and Twist is that the dial on the Spinner is easier to read.
That would be great, if the Vision Spinner works on the charger I already have! Will the tank that I have work on the Spinner, do you think?
