I'm glad I got my Electric\Devices Blaster to 50 a long time ago, so I don't have to worry about this.
But, if I was levelling him up now, I'd dump Auto-Turret, as its too situational without being able to teleport it - I used to use it as a distraction by dropping it then teleporting it around a corner, for instance.
Besides, Trip Mine is the best power in the Devices set, anyway, and you need Teleport Foe, not Recall Friend, for those.
