Co2 Systems- Prices

[Animation]

Anybody know the price most people would be willing to pay for an average Co2 system, i have never used one before and more to the point i have never seen one, prices and pictures maybe some instructions would be great!

I payed £150 for a JBL Proflora set 2.
A lot of money but it was easy to set up and easy to use.

PS: This is the one. But mine has the refillable cylinder.

More money than i thought however looks good, I am only 14 so can only really get my tanks good week by week due to pocket money?, Ishould of really asked what the Co2 does first?!
