I hold my logbooks. I complete them after the flight and when I get to 50hrs I let my CAMO know. They then let me know what is due and if anything fall between 50hr checks. A straight 50hr check I do myself. Anything that needs a lifed item replacing I take to them.
I do not pay any of the exorbitant charges being discussed here. My CAMO are honest and admit that there is little extra in the way of Part M that they should not be doing anyway.
There is no requirement for the CAMO to hold your log books.
Like I said, a lot of engineers have taken the opportunity to write there own interpretations of the rules and price accordingly. The cynical like myself would say that many are exploiting the situation.......
A&C you and I never going to agree on this, however don't think that I am stupid enough not to know the rules or have a lack of business knowledge to allow you to insult me into having the wool pulled over my eyes.
