Yep. I used to lug:

(2) Power Supplies $100 each
(2) iCharger Duo's $300 each
(2) Discharge Resistor Banks $100 each
Total - $1,000

Now I use:
(1) RC Discharger Off-Road $400
(1) iCharger Duo $300
Total - $700

Saved $300 and can cycle two packs up to 45a on both channels at the same time. Takes up less space and weight in pit bag. Better IR's and more importantly the charge cycles have higher capacity. Batteries do not get as hot as when using the resistor bank so last longer before replacement.
