There are two types of sensors, the 'standard' sensor for
production cars which lasts forever :)  and the wide-range
sensors which have a life of ~500 hours for unleaded and ~50
hours for leaded. I know that Bosch sells the wide 'Motorsport'
lambda sensor for ~$350 Australian.

I think there may also be a long-life sensor for leaded -
try talking to Link Electromotive in New Zealand
(link at lynx.com.nz), the sell their 'Lambda Link' meter 
($90 NZ) and also sell the sensors (~90 for unleaded and 
> $200 for leaded).
