The recent model Parks don't seem to get good reviews and the Rennkompressor looked great for a personal pump if you've got presta valves. I wasn't entirely comfortable with it for use among a wide variety of people with different valves.
The pump I got for the office (a Specialized) has a really big gauge that's on the floor.
I'm not sure what you looked at, but my Rennkompressor works equally well on presto or schrader valves.
With the high pressures of road bike tires, if the gauge didn't work, there isn't much point in that pump for me.
