You already know what i'm going to recommend but i'll say it anyway.
+1 Mountain Morph (I've got the turbo version which has the gauge)
had a topeak dx harpoon which was alright, looked cool but average pumping.
then had a crank brothers power alloy pump which just was crap, high volume/high pressure switch which worked but it lacked power and took ages.
mountain morph is great, bit long and foot seems a bit pathetic but speed and ease of pumping is fantastic. the gauge works well and although small is clear enough. Brilliant.
/edit motivforz - the other pumps are at the parents house but as an approximation of mine with 2.3 high rollers:
topeak harpoon - gurnage = 7, time = 2.5 minutes
crank bros - gurnage = 9, time = 5 minutes
topeak mountain morph gurnage = 2, time = 45 seconds.
