It's a great scope -- rather large but one that provides superb light transmission and resolution. The A4 reticle is bold and will stand out in poor lighting.
I like the looks of it better with a 30mm tube, but that's a personal preference. I had a 1-inch 8x56 for a while but eventually sold it.
Used prices are all over the place right now. The last 1"-tubed 8x56 I saw that sold was near-new and went for $675 shipped. I think I paid around 580 for mine, but that was maybe 7 or 8 years ago.
