HI HLJ - I have the original - it works pretty fast! - From flat to 85 psi takes about 3 minutes, I guess - I need to change arms about 3 times though if I go at this rate. I like it because it can handle the high pressures I need (so many pumps don't), has a built in pressure gauge, and stows so well.
