RE: In the market for a balancer...
I guess it doesn't really matter because you can get adaptor cables to convert any balancer to work with any pack, it's kind of a pain though.
If you go for the normal jst lineup that seems to be where the highest number of pack mfg's are and these include
align, esky, eflite, venom rc, commonsense rc, electrifly and great planes, park zone, dual sky, dynam ect all of which will work with the equinox without a seperate adaptor.
If you want to go to TP compatible that's an easy switch with one adaptor cable on the EQ, and to go reverse polarity JST on is pretty easy too, so just whatever you decide.
