Haskell Pumps

Hello,
Can anyone tell me how much a Haskell pump is going to cost me and a good source in the UK?

I believe the Oxygen hackers book tells me how to build one! This seems very interesting but possibly not the best way to go!

Thanks in advance,

David.

They have always beeen too expensive for me David!! Haskel make a range of gas boosters. Cheapest 230 bar O2 safe (I think) is about 3 grand.

Consider the jetsam (KISS) one... If this meets your needs.
