I agree! I have a Nikon HG 8x42 and the new Nikon M7 8x30 and when I compare them in the daytime I see very little difference at the edges or in the overall view. Likewise, I would say if you are going to use your binoculars primarily in the day, just get Nikon M7 8x30 for $300 on eBay and save yourself $700 over the HG 8x42 or HG 8x30. If you want better low light performance and a little easier eye placement, get the Nikon HG 8x42. The HG 8x30 is way overpriced for what it is, as Allbinos said.
