Assuming you look in the used vinyl section (lots of copies around) have you considered cassette? Harder to find are the first single, first LP and the posthumous Vortex LP (i.e. Ultraprophets had the biggest pressing).
For the curious - Christmas mutated into Combustible Edison (a member of the 'lounge' movement of the 90's) after James McNew went into the sonically fertile ground of Yo La Tengo. (His side projects are now called Dump). Christmas toured Ultraprophets in an opening slot for Husker Du!
