Well, seeing that D3 (and most likely Blizzard) has hit the crapper, I was wondering about telling you about Guild Wars 2 which was actually made by the previous Blizzard staff that was involved in D2, but then I remember you don't really care for multiplayer games. Arenanet has also showed they care about their customers by limiting sales after servers got too full... unlike Blizzard who pretended the problem doesn't exist.
Still, I'd suggest you to give D3 1.04 a shot. Most of the stuff's been toned down quite a bit and at least the prospect of leveling again gives some kind of progression.
It also wouldn't be a problem if you want to link your profile and screenshots of the AH to consider what stuff to buy and sell in order to upgrade. Upgrading gear is a lot cheaper these days.
