The 7x30's are real nice glass. I used to have a pair years ago, but sold them ten years later for more than I originally paid for them and bought a pair of EL's. The Swaro's keep their value-I first paid $495 for a pair of 7x30's brand New in the 90's and now they go used for more than that. The top alpha bino's are like an investment- they tend to go up rather than going down in value, can't say that about many hunting items we buy-except for guns of course.
The 7x30's that are for sale probably don't have the Swarobright coatings that Swarovski first started using in 1999 and the 8x30's only started getting that coating in fall of 2002. It definately makes a difference.
It would have been good if Swarovski kept making the 7x30 size-I thought at the time they were better than the 8x30's. But now that the 8x30 NEU has the best coatings, they are probably a bit better; just a shame that they dropped the 7x30-it is a very good hunting configuration.
