Actually recond may not be what you think it is. I can share a little bit since I used to have a client who done this.

Most are sourced from Japan due to our market dominated by Japanese brands. I think it is also due to the fact that Japanese limit their cars life to 5 years. What they did was take the case out and refurbished it. I think they changed a pulley and put everything back together in a nice box. These usually dont last long which is why they give 1 year warranty. However if your usage is not much, these can last for a while. Its earning big bucks. Unbelievable but true. Its truly a con job.
