Mini pumps

Has anyone tried the Park PMP-3 Pocket Protector Micro Pump? I'm mainly attracted by the price, shape, the few reviews I've found and the fact it's Park.

After the discussion in the CP thread I'm prang and thinking about getting a mini pump.

I have a 29cm Specialized one I could chuck in my bag so I'm really after a "get-me-home" micro pump to go in the back of my Jersey that can get up to c.80psi.

Wish list in order of importance:

• Cheap (as close to £10 as possible)
  
• as small as possible (to go in a Jersey)
  
• won't break
  
• decent valve locking mechanism
  
• able to pump up to 60-80psi fairly easily (if can can go higher with hard work even better)
  
  

Cheers.

I have this, had 110 out of it in Puncture Rage Mode.
