I believe it's around $260...Not sure though. Look in the FAQs page or do a search. I recall reading a post not too long ago with vanchetta replacement on a speedy. Hope that helps.
I recently repaird my Speedy 30. I chagned the whole vachetta on it (handles, tabs, piping) and the cost was 405 euro (the new Speedy 30 is about 560 euro).
