Depending on how lax your DM is, you could always have something like "Bill's Guide to the Use of Items, Magical and Arcane", name it a masterwork tool that provides a +2 circumstance bonus to your UMD skill, and it would cost you 50gp.
This is all open to how you interpret a masterwork tool, though.

This well-made item is the perfect tool for the job. It grants a +2 circumstance bonus on a related skill check (if any). Bonuses provided by multiple masterwork items used toward the same skill check do not stack.
