I would go for the pila, I struggled through 2 Efest Lucs before I gave up and grabbed a Pila. The Luc's voltage detection is really inaccurate. Both of the ones I had would tell me my Batts were fully charged, 9 times out of 10 when I checked them on a multi meter they would be between 3.9 to 4.1. Very rarely did a battery meter out at 4.2 volts. I would have to take the battery off and put it back on a few times in order to get it to a full 4.2 volts. Because of it's inaccuracy, the fancy LCD screen was next to useless. Other than the spacers, the Pila is no muss no fuss. I put the batts on, wait till the lights blink green and voila, full charge every time.
