Mmh, not that interesting, the new models. NCV and AC-LoZ aren't that useful for electronics, and the added bar graph isn't worth the $10 extra (-E vs -C). The -S goes for $70, seems a bit much? I like those EBTN displays, but I don't think I'd pay so much extra just for that? Not to mention that while it looks nice, it also requires more power. I reckon that battery life on the -S model will be 50-100 hours.
