Same here, but our reasons were more being able to debug them in case of
problems.

Nowadays I hardly buy components. I use cport, indy9, VST and one routine
from dmath/fpmath and that is about it.

The main reason for that is that most components are not suitable for
systems where 10ms is a long time. (indy runs in a separate thread, since it
can also block longer, cport is async via windows msgs queues)

One of the components I had problems with was TeeChart. It was simply too slow
for us for everything except the slowest systems. (ate more than 300-400ms to draw
a simple chart, D7 version)
