X2 on the Viar 450p. I like to check and make adjustments the day before leaving a location and hate to fire up the engine to use the on-board Compressor. Also I felt the 120 Pancake Compressors are to large for me. Storage space is too valuable.
The Viar is a little slower however it works great and is all you need.
