Hi, I'm friend of Bhante Sujata.

Does anyone know if there are any printed tipitaka in roman script
other (cheaper) than the PTS?

Mahidol either never had one or have run out, the new excellent one
from Mahaculalongkorn is not going to be released to monasteries for a
long time if ever, and the Sri Jayanti one has so many mistakes on
every page.

thankyou for your attention,

Bhante Santi.
