On a very quick search I am not sure if harbour freight still has them. Princess auto in Canada shows eight 0-30 psi remaining in stock and they are about 2 1/2 inches in diameter.

They do mail to the states as well and an instant mailing quote is listed on the item. The gauge is up a little to 15.95 canadian but their mailing is usually reasonable. I brought mine on sale.

They have those cursed monthly flyers where you grab stuff on occasion because the price is right. I never seem to walk out with just the item or items I went for. The last two times it was copies of the binks automotive enamel size spray guns for under 15.00 each. About a number 18 nozzle. The cups alone are about ten dollars each here.
