You'd be hard pressed to find anywhere with a higher quality of life and more exciting cultural offerings on less than $2k/mo. Buenos Aires beats on Colombia, Mexico, and SE Asia in it's European-ness, imo. Mexico is still pretty deeply culturally conservative. Southeast Asia is, well, East Asia. It's cheap, but the cultural differences are vast. I don't particularly enjoy hanging out with the "digital nomad" tech bros that populate the region either. I haven't been to Colombia so I can't comment.
