Deffo worth it imo. I have it's posh cousin, the EX-RR, although the older one with the conventional trigger. Bear in mind the EX-II only has 2 channels, so you can only run conventional models. No 2/3 speeds, 4WS, winch or anything like that.
I prefer the ergonomics and lighter weight, although the build quality is creakier than before (but still good), and the other 2 brands have become less creakier than ever...
The menu and features are somewhat easier to use and you can customize everything to the hilt, which is good for ergonomics and it stands out from other TXs on the bench.
Transportation is a nightmare though, especially with the drop down or stick extension, you either need a bag with a DIY insert, or you disassemble it everytime and reassemble, taking the utmost care, like me.
Loves to absolutely chew through AAA batteries though, so I recommend buying those in bulk. It will easily drain 4 AAA batteries in 2 days, and that's with me switching it off in the pits half the time.
Definitely worth it, but I'm not in the US, the US distributor is RCAmerica, the Xray guys. They seem to be OK from what I've read....
