In the number pad area of Torgue machines, the screen will always read "80085" (trans. "boobs").
All legendary items sold in these machines costs 613 Torgue Tokens each.
The level cap on legendary items in Torgue machines used to be level 48. This was fixed temporarily on January 29th with a hot fix (a server-side patch that required an internet connection when loading the game). This issue has since been patched with the 1.4 patch released on April 2nd.
