Very HV transformers

I've seen several people mention getting various HV transformers
that come from unusual sources (e.g. from X-ray machines).  How
do you manage to get ahold of these (I'm especially wondering who
you ask), and how much do you usually pay for them--or do you
somehow scavenge them?  Also, how do you use transformers
with such incredibly high voltage for Tesla work, if you do?  (I
remember a mention of a 90 kV transformer at one point!)
