Nice to have you here. It's a bit slow right now, school out and people vacationing I suppose. Cecil pretty much summed it up.
I have just about all wc's except for what I have bred myself, and kept. They can be very difficult (especially males) to acclimate at times, and must be handfed until they get going. Some will starve to death rather than accept captivity, very SAD !
Some take to captivity better than others. BUT,,,,, everyone I have that has acclimated has become a wonderful pet with plenty of handling and attention. Takes time, and patience.
If you are interested in a lizard as a pet, than a collared is an awesome choice. They are not only BEAUTIFUL, but active and bouncy and just a pleasure to watch. They can become so friendly if worked with . And YES, we sure do love them here. 
And remember you can always start with a captive bred youngster that would be hand tamed already!
Hope ya stick around, enjoy the forum
