Hadden like camps

[astrohax]

Does anyone know of any other camps with decent loot that are like the hadden spawn?
By this I mean spawns in a static, safe location, multiple hours between spawns.

I would prefer a mob that wont require someone lvl 40+, but mention them anyways so i'll have something to look forward to as i level.
I also prefer mobs that a single person could kill, but I do have some friends that i can scramble together so maybe a 3 person maximum required.
