Any Fiber Laser Successes?

We were at fabtech last week and were shocked at how affordable (in relation to 5 years ago) fiber lasers have gotten, especially the imported chinese ones. One thing that I noticed is that all of the decent chinese ones used Max Photonics laser head & source. We all know the imported chinese lasers can vary on quality, reliability, and parts/service.

So that led to the question: Why not buy an older name brand CO2 laser (mazak, amada, bystronic, etc...) and retrofit it with LinuxCNC, new servos & drives, and a Max Fiber laser source and head? A lot of places are practically giving away older CO2 lasers that work just fine, which would be a perfect starter. That way it is a better built machine with modern controls and laser, for most likely less money than a chinese import laser. 

Has anyone successfully done this yet? We did a Mazak VTC mill earlier this year and are absolutely thrilled with how it turned out running Probe Basic.
