I guess it depends on what features you are looking for, and brand loyalty often plays a part. The RF tag reader is an interesting novelty but for me there are more important features to look for in a charger. I'm not one to be much interested in compiling reams of data on my battery usage and because I parallel charge several batteries I dont think it can be of any use in setting an automatic charge rate (it's only two button presses to do that manually anyway!). Is there some benefit of the bump controller I'm missing?
At $145 plus shipping it also makes what is already a pretty expensive charger VERY expensive. I do get how nice it would work in a portable charger case but I dont use one of those, mine is a bench setup.
Personally if I had the budget for a PL8 and a Bump controller I'd buy neither. I'd get the iCharger 4010 Duo and keep the change for more batteries. For my purposes dual channels and double the charge power is worth more than RF tag reading and touch screen (not to mention cross channel resistive discharging at up to 1000W which only the iCharger Duo supports), but each to their own.
