I'll add a recommendation for the EBC track pump. Bought it in the sale last year and for less than a tenner it seems terrific value.You are best with two pumps - a track pump at home and a portable to carry with you.
Track pumps - as well as the Lezyne there is the Joe Blow - but here's such a good deal it's hard to pass up.

Sale price this weekend only - so you'll need to be quick.
When I'm on the road I struggle to get much more than 50psi out of my Topeak Master Blaster so I'm currently considering replacing it with a Lezyne Micro Floor Drive HP.
