5 of our 6 Tegus

Beautiful Tegus! I'd love to get a tegu, i just don't have the space/money/time to take care of one right now - college can suck like that :) I've done some research but I'm stuck as to which kind i should get when i can . . . between a bw arg, blue or red: which would you say is the easiest to maintain/care for, and the most docile? Being docile is very important to me. I'm leaning towards a bw argentine right now, mostly based on looks (i really like the ones with lots of white - chacoan or white headed?) How come blues seem to always have dark noses? Any help would really be appreciated, seeing it is you have such a variety I'd really value your opinion. Oh, and any suggestions where to find one? BlueTegu.com is the only place I'm really aware of. Thanks!
