Kenwood KH-K1000; not just an alternative, a superior 'phone (imho). More balanced, more comfortable, better build, and so on. No rattling screws either. AC sells them, and should ship to Israel.
That having been said, the D2000 isn't as fragile as people make them out to be; the only ones I've seen fully come apart are the result of shipping damage or outright abuse. You list "40 or so cases" - out of how many tens of thousands of units shipped over the last few years? I'd take the Kenwood over them for a variety of reasons, but I wouldn't write the D2000 off entirely; if it's what you like, get it. AC sells that too, so that's better than fleabay (you'll get the real deal and have some degree of recourse if they're damaged (http://www.audiocubes.com/faq.php)).

And lest you think I'm a salesbot - I'm not. I've been happy with the few purchases I've made through AC, and they're the only source of the K1000 outside of Japan that I'm aware of, and they happen to ship internationally. They also sell the Denon and will apply their warranty terms to it, so if it does break, you have that (as opposed to eBay where you basically take what you get).
Another alternative, and probably a cheaper one, would be the Ultrasone HFI-2400. It has more bass than the Kenwoods (and virtue of that, I would believe the Denons (I have not compared the Ultrasone against the Denon, only the Kenwood)). The mids aren't quite as spot-on, but they're very good. Very comfortable, built like a tank, etc. The only potential qualm with the Ultrasone (and this is any Ultrasone) is that not everyone experiences S-LOGIC the same way. See here for more:
http://www.ultrasone.com/index.php/en/products/hfi-2400.html (and they do list a distributor in Israel: http://www.sontronics.co.il/ (I don't read Hebrew so I can't help much beyond what the Ultrasone site says)).
I'd list none of the above as fatiguing. I like the Ultrasones least of the bunch (too much bass for me; I am an anti-basshead though).
Regarding the Beyers - I've honestly never heard the 880/990; the T70 was harsh and etched though. CSDs show the T70 having a nasty ridge while the 990 seem free of it; I'm guessing they're not as bad as a result. The D2000s at $350 are not a bad price - the Kenwoods are slightly better but more expensive, the HFI-2400s are competitive but not as well rounded, albeit slightly cheaper (list is $329 US, they're usually around $229 though). I think compared to something like the T70, they're much better suited for more or less anything. Along with the Kenwoods, the Denon headphones really hit "all-rounder" out of the park. I think the HFI-2400 is the next closest tier, it's just the extra bass (but for the genres you listed it might be perfect; I liked them very much with rock and trance).
