You checking out the one Shawn Parker has for sale on RC? I kinda had my eye on that as well...
I have never kept albigularis, but I have considered it. If I were to get one I would set it up like a Nile or Ornate, but without the huge water area (big enough for soaking would suffice). HUGE enclosure, deep substrate (a foot or more), basking to 140F, coolest nights around 75F, lots of hides, large logs and rocks.
The one Shawn has is around 3 feet - check its age. Should NOT be over a year old.
Temperaments vary. If you know how to maintain a trusting relationship with varanids then no problem. If you're new to them then you're in for a treat!
Under a year old feed daily - lots of food. Variety is best, but a staple of rodents is best; as long as your environment is set up properly.
