I had many pairs of these over the last few years. I would recommend buying the hd version and not for reasons you would assume; the non hd models have HORRIBLE red LED interference when your glassing in the general direction of the sun. So far I haven't noticed this problem with the hd's.
The non hd version also have had problems leaking their internal nitrogen and this happened to me. I booked a 12-day dall hunt in Aug of 2010. On day four the entire right side of the binos completly fogged up with no abuse or neglect on my end. Because it was the right side I had no rangefinder, only an expensive monocular and had to use the guide's POS leupold rangefinder to kill my ram.
Leica, as expected, repaired them at no charge. Optically there is very little noticable difference between standard and hd.
The good? They are the best for the money. At $1200-1500 for non hd 10's they are a good choice and buy, the hd's will run a couple hundred more. IMO the optics are not as good as the zeiss rf but the leica rangefinder performs much better at long range.
I have the new swaro range on pro order, scheduled to get them mid March. The swarovski's are hands down the best of the three in terms of optics, angle compensation and rangefiner, the only drawback; button is on wrong side, again, for bowhunters (and of course $2K dollars).
