theres often some on J-spec.com.au
i emailed him about them and this is what i got back.
"There are a few TE27's available from time to time although most of them are
rusty junk that we would not be happy buying - the good ones seem to be
worth fairly good money, with the average price range at around 400,000 yen
to 800,000 yen .. we have been lucky enough to get a really nice example for
a client recently at the lower end of this range but it took weeks of
looking and lots of unsuccessful bids.
