The only problem with the ego is that at $25 a pop, it is not particularly cost effective to replace the batteries when they wear down. A 10440 (AAA size) or 14500 (AA size) mod will be
much cheaper in the long run (batteries are only $3-$5 each), and about the same price (or cheaper) in the short run. For a frame of reference, compared to a standard battery, a 10440 will last about twice as long, an ego about 3.5 times as long, and a 14500 about five times as long.
- Janty Stick/DSE808 - 10440 battery, can be charged via USB and used as a passthrough, $40-$75
- Bartleby - 14500 battery, can be charged via USB and used as a passthrough, $50
- Lazer - 10440 battery, only $35
- Nautilus - 14500 battery, $67
- VP1 - 10440 battery, $85 including batteries, charger and 801 attys and carts
- VYPR - 14500 battery, $84 including batteries and charger
And those are just the ones off the top of my head. There are lots of choices out there. If you're willing to consider a larger mod (with even more battery capacity), there are more choices yet. The
Indulgence is an excellent place to start, since it comes with connectors for the main four atty types, and it's pretty cheap. You can also use it with larger batteries, two batteries for 6V, or 5V as a USB passthrough with additional battery cups.
