yeah it's confusing, he doesn't know what he's selling, but seems straight up. the 3rd cable isn't listed, but he told me he found one and was adding it. from what i've seen lately, these'll probly go for $150 - 200, but you never know. if you search around here you'll probly find better answers than i can give, but, the main diff between the 300 & 100 is the 100s have more noise. although i dought you'll notice it. i used this mic for my last tape , center channel, and i didn't hear the noise. it came out muddy, due to all 3 mics being cards i think. one advantage of the 100 is it runs on AAA batts, readily available.
remember this is jmo
