I have 3 that I use.

Revolectrix PL8 - Desktop use
iCharger X6 - Desktop use
Revolectrix DPL8 - built into a charging case with 24V power supply and 2 4-port MPA boards and a Bump Controller.

I started with the PL8 and then bought a DPL8 when they were clearing them out for the Touch series Powerlabs. They are workhorses, easy to use, and very reliable. They are my main chargers. I purchased the X6 because I wanted to try out a Junsi/iCharger to see how I liked the menu system and performance. For the money, the X6 is a pretty nice charger.
