OK, so that's 15 minutes of my life I'll never get back .

Good and interesting read, though. I did learn a few things .

520 vs 710. No contest. M-2 710 still is the baddest and meanest SOB in the land (with much respect to the 520)

Jon, you'd be a good candidate for putting the new 710M4 through its paces. Why? Because you've already worked a 710HS mighty hard and know what it can do. I'd really like to hear your thoughts on how they compare.

Are you thinking about getting one?
