That's about 63 more than I would expect. Those things really are meant to be reused.
Jay is not talking about fitting the ribbon cable to the connector, but
to connecting/disconnecting it to its mating connector. Class 3
conectors are rated for about that many mating cycles, Class 2 for 3 to
5 times that, and Class 1 for upwards of 400 cycles. You might be
surprised to know that the figures are about the same for many other
types of small multipole connectors.

While this may be true, it is usually a bad experience when the male part

It's not _that_ hard to replace. The trick, of course, is to cut the male
connector apart while it's still soldered to the PCB, and desolder it a
bit at a time.
If it's a straignt, vertically-mounted connector (not the right angle
type), it's often possible to desolder individal pins and push them out
of the moulding while hot. Then you can solder in a replacement pin,
taken from another connector.

No, actually you want to be fully allert so you don't lift any traces on
the PCB.
It's not _that_ bad a job. I've had to do it a number of times, and I
don't worry about it any more.
