There are several good pumps on the market, but be careful because the vast majority of pumps on the market cannot reach their psi claims, this applies especially to the mini pumps.
The Topeak Road Morph G, which I own, is a great pump but it looks ungainly on a bike as would the Lezyne with the external hose shown in a post above in my opinion. The Zefal is an old standard frame pump, which I also own a 30 year old one, that's been around a long time and is very rugged pump that took a dog beat down upon the nose without any effects except blood; it is a direct connect pump, meaning there is no hose, so like any direct connect pump you have to be careful when pumping that as pressure goes up and the difficulty factor to pump increases some people will have a tendency to saw back and forth which will rip the valve stem, I've never had that issue with those types of pumps including direct connect mini pumps but many have, the good thing about that pump is that it doesn't take as much effort as a mini will thus the sawing effect would be less. The Lezyne does make a very nice mini pump that has a hose that is stored internally so it's not visible, depending on what kind of tires you have, like high pressure road tires then the Lezyne (alloy) Road Drive, which comes in 3 sizes but only get the large size for ease of pumping at higher psi, look a lot nicer and works better than any other mini I've use and I've tried a bunch. See:
http://www.lezyne.com/product-hpumps-hp-rddrive.php They also make a fancy version of that pump called the Digital Road Drive that includes a very accurate digital pressure gauge, but of course this one is not cheap at around $70 American dollars vs $32 for the regular Road Drive.
But all the pumps the others have mentioned so far are very good pumps and are quite worthy of being purchased. If you like the Zefal you need to be careful when pumping that you don't get into sawing it back and forth, you have to brace your thumb over the top of the head of the pump and your fingers underneath on the tire. Even a pump with hose if someone isn't careful can saw with those too, but as long as you keep slack in the hose you'll be fine.
