Hey Joseph,
Sorry to hear about your loss. I haven't personally owned a Colombian, but i can confirm what you've heard, as well as what you have witnessed.
Most people comment that Colombians are more aggressive, though i have seen, and held many that are calm and docile.
I've also seen my share of aggressive Argentine Tegus. I think its a combination of the particular animals personality/ability to trust you, and your ability to put in the time to build its trust. Some won't ever trust you, while others Argentine or Colombian will come around fairly quickly.
If you're able to handle them at the reptile shop thats a good start, though tegus do occasionally change their attitude once you have them in a bigger enclosure that they consider their home.
I'm sure someone who has had a Colombian or two will chime in to give you more firsthand experience/feedback.
Best of luck with your next Tegu!
