Re: Atomic bindings - just my .02c, but between my wife and I, we have four pairs - 6-14s on my Big Daddys, 4-12s on her Sugar Daddys, a 4-12ish binding on my 10.20s (I think, orange with black ski, a few years old), and some Centrix 3-10s on her little blue intermediate Atomics.
She's light, and an intermediate skier, but her bindings have given her no trouble.
I'm not light (250+), solid advanced skier, used to break Look 99RS' in the 80s with disturbing regularity (strip out the threads in the toe-wing screws, the heelsprings used to shatter), have had no troubles with Marker, have had no troubles with mid-90s Tyrolias (I know, shudder, but a friend of mine was a Head/Tyrolia rep, wound up skiing on his stuff a LOT), not owned too many Salomons, but those I have owned were the "race" models with metal heelpieces - the plastic heelpieces on the 957ish era bindings - mid 90s - used to break; the tab that the heel of the boot pushes down on would break off, making it into a Marker MRR clone - it was still usable, but you'd have to reach down and pull the release lever up as you were stepping in. The metal ones were -bomber-, though; I can see why Salomon people are Salomon people.
Both my BigDaddys and orange 10.20s (that's what they are, maybe 99/00 model year 10.20 Beta Rides in 190cm) were demo skis. The 10.20 has a demo binding on it, a piece of plastic that surrounds the demo-release has broken off, but the binding works fine. I'd guess these skis had 40-50 days on them when I bought them - lots of topsheet issues, bases were good, but they're just about tuned out (they were $99 with bindings 3 years ago). The BDs had less use, I'd guess 10 days on them.
Since I got the BDs, I've skied them, ohh, 40-50 days, some hike-backcountry(ugh), some catskiing, etc - they've seen a fair bit of use. I've prereleased a couple of times when I did not think they should've let me go, but in terms of _problems_, I've had none. They work. I ski them at 11, make sure the boot is clean, shrug, dunno what the problems are, but I've not had any.
I was hesitant to buy the $99 10.20s, ehhh, but I decided that I'd risk it - no regrets. I've always been a Marker guy, had good luck with them, but I liked the 10.20s/Atomic (ess, as far as I know, by a different name) enough to buy the BDs to replace my K2 AK Launcher (with a Marker race binding, forget the model, basically the M51R in this day and age, no pistons, nothing fancy, just a binding).
I've had no issues.
When I was working in shops, none of us really _liked_ the Ess binding, which I believe turned into an Atomic binding, but I don't remember any "issues" with them.
Maybe there is something up with the Atomic binding; I don't know. I've not run across any issues with them, though.
.02c, YMMV, etc etc etc, but out of 4 pairs, the only problem is that broken piece of trim plastic (which does not affect function at all, it has been that way for 2 seasons, and when I'm skiing my BDs, a friend of mine skis the 10.20s - they get some use).
