Wow! the price of these things!
Make your own, Youtube it or ask on here how to!
I made my own, the beauty of that is, when it goes wrong(if it goes wrong) you know how to fix it - right there and then!
ITS NOT ROCKET SCIENCE, PEOPLE!

I no longer use a tank system, down sized to a barrel/trolly system. Also made that myself. You tube it!
Also, one last thing... Buy a Gardiner pole - proper job!
Couldn't make that - Sorry!
