PC Problem...

What I still can't figure out is why compressed air bottles are twice or thrice as expensive as bottles filled with propane/butane...

Must be the bloody shops around here mercilessly ripping off stupid customers.

It's more expensive because ethane derivatives (the gases in compressed air) are harder to contain and package than propane and butane. Also, they're harder to produce than pure propane/butane.

The cheapest I've bought compressed air for is 3 big cans for $10. Each can lasts quite a while if you use it properly (spray it in short bursts). So far I've only used up one can.

Oh. Thanks for the information. I didn't know there were such complications. But still, the cheapest I've seen around here is about 10$ for a single can! Those propane/butane cans sell for 3 for 10 euros. I seriously don't want to pay 10 bloody euros for one can of air. That's why I'm thinking they are total rip-offs here.

Well, I don't want to derail the thread any more with my whining...
