WTB: Manual Boost Controller

Like the title states, just looking for a manual boost controller, doesn’t need to be anything special, as long as it works. Let me know if anyone has anything!

i have a turbo x one for 50

Is it just a basic MBC? Not a dual stage or anything like that? any pics or links to a website with a pic?

EDIT I just saw your other post with the picture of the boost controller, no need for a pic.

i have a forge mbc brand new and i also have a apexi avc-r gearbase boost controller 3 weks old
