TRU-FLATE tire pressure guages are made by Stant. If you search the Web for "Tru-Flate" you will find several stores that sell them.

Greetings all, I've ordered LEGO Designer from Pitsco, and was wondering if any of you have used it. Is it similar to LDraw, or am I just getting the old LEGO CAD in a new package?
