At least in a group owned TB you can afford to by the maintenance manuals. The CD (includes maintenance and parts manuals, SBs etc) is supplied by EADS-SOCATA for the princely sum of 1000 Euros, oh and 400 Euros a year to keep it up to date....
You aren't likely to find many maintenance organisations that will buy the manuals to look after one aeroplane type (you need a different CD for each of the TB9/10/20/200/21).
There have been issues of spar corrosion requiring new wings (and on some not so old airframes), parts aren't as easy to get as for the American stuff.
