I think its 12.5k on vendor bought mats alone.

with the rest of mats you can get yourself, such as bolts or titansteels.. or you can buy them from AH or friends.
I made one but it was a long time ago but i had all the "Other" mats in the bank so it didn't feel so bad.

Havent heard anything on them lowering the price of the Vendor bought mats.
