I have the 7x version and love it for many reasons - search and you will find my review from about a year ago (sorry I can't look for a link for you just now).
All the same I'm going to wear a black hat for a moment before you proceed. I expect the 8x you have seen is an even better instrument than the 7x but bear in mind the following. A well-respected binocular repair technician with many years experience cautioned me that he wouldn't have bought an EDG because of his experience in Britain (at least) of great difficulty getting any parts needed for service if things go wrong. This may be different in the USA. Weigh against that the high reputation Swarovski enjoys for customer care, probably built into their new item pricing in advance.
The EDG may feel a bit heavier and have a narrower field of view.
I still don't regret at all getting an EDG while still available and you have already found a good one at a good price. But weigh up the info above if you weren't aware of it already.
Read Tobias Mennle's review of the 8x42 EDG at greatestbinoculars.com and also for comparison Roger Vine's review of the 10x42 EDG at
http://www.scopeviews.co.uk/NikonEDG8x42.htm
Unfortunately Roger Vine doesn't tend to date his reviews and from Tobias' article it appears as is altogether likely that Nikon may have tweaked their coating recipe at some stage along the line.
Good luck with your decision and/or purchase!
Tom
