I just found their UK store where they sell for GBP15 plus GBP5 shipping to the UK, so GBP20 / USD 30 per unit. I created an account to get shipping info.
Register for free and enter a U.S. address to see if they deliver. Jaycar advertise in a few of the U.K. electronics magasines where the mags have a "project" and Jaycar will supply all the bits and pieces for the article.
Size of the speedo unit is quite small : 63(L) x 46(W) x 25(H)mm where 25mm is approx 1 inch in old money, so 2.5" x 1.85' x 1" (quick maths-in-head so check)
