I own 2 Rode NTG-2 mics one on each camcorder that i use. I really enjoy the sound for vocals on the camcorder. I find the vocals a bit flat and dry, but very directional due to the mic. Now i have not used the AT875, but if one were to move up go with the Sennnheiser the number escapes me but it does run about 1,000, but he Rode NTG-2 runs about 250.00. I also know if you check youtube they have examples of each and demonstrate the sound as best youtube can but that might give you an idea. I went for very good sound quality as i could. I did not want my mic price higher than my camcorder in this case.
