What high-level enemies respawn in Borderlands?

Much like this question’s author, I’m interested in gaining good XP at a high level. But rather than doing challenges (which often get done in the course of normal playing, especially the ‘kill X of Y’ type) I’d prefer to do it specifically by fighting enemies.

George Stocker mentioned in his answer that Motorhead respawns every 15 minutes, but surely he can’t be the only unique enemy/boss who respawns. Skyscraper giving 23k XP would be great but as far as I know he’s a one-off. It seems that an exhaustive list of respawning enemies would be quite useful.

  • How long is “a few seconds” for Kill Skills?
  • Where can I find more “Omega” equipment?
  • Start another Borderlands playthrough
  • Where is the claptrap in Old Haven?
  • Beat Brick as Lilith
  • What is the fastest firing rate for a submachine gun in Borderlands?
  • Is there a list of farmable enemies, and where to find them?

  • Mordecai's Gun Crazy skill + burst fire, what happens?
  • Where is the claptrap in Old Haven?
  • What are good builds for 'Roland' in Borderlands
  • Where can I find more “Omega” equipment?
  • How do I glitch Phasewalk?
  • Do the Boxes and Containers in Borderlands work much like the different kinds of Chests in Diablo 3?

    All enemies respawn when you exit/reenter the game (with the possible exception of the destroyer). Some respawn if you simply leave the area (such as Crawmerax). If you have the Secret Armory of General Knoxx DLC, I would suggest farming crawmerax (best experience, and the only way to reach max level of 69). The added bonus is he also drops a lot of high level loot, including pearlescent weapons.
