AP movement replacement

[lolz123]

I was looking to get an AP. However, the thought of the untrustworthy second at 12 breaking down on me is putting me off.

 

I hear of franken projects and such. I am more so interested in just switching out just the movement, as gen hands and dials are not TOO big of a concern for me at the moment. I've looked at forums and it appears that people use the Maurice Lacrox with a Dubois-Depraz module.

 

So i was wondering how often can someone come across a movement like this and usually for how much? Plus i know it'll be really hard to find a watchsmith capable of the switch. But i would really prefer to have more peace of mind with a better movement
