Slim 510 battery mods?

[mrtuna]

I need a slim 510 battery mod for work. All I have found it the Precise from Super T. I don't want to wait a few weeks. What else is out there?

Thanks in advance

I have a Spade and it's about the same diameter as a AA battery. It uses 10440 batteries. If you are a hardcore chain vaper (like I am), the battery life may not be too impressive. I've heard good things about the XHaler, but I've never used one.
The Ego might be a good choice too, but you have to buy the ego batteries for it, which is a real turn off for me.
