poor bloke, he comes on here thinking 'yeah get some more sales man' and all he gets is criticism.
Im sure many people have thought of selling off these systems to make money, but its just not going to work selling that off at those prices. You have to have something thats worth offering for sale, that looks good, well made, safe, and with a few extra features here and there.
When you look at all the other companies like purefreedrom or stream wfp systems, they are well designed, well made with quality steel cages, with professional fitting teams, the systems are even marked off with more advertisement and branding, and they source there own equipment-
its seems all you have done here is bought a tank from ebay or somewhere as cheap as you can get, bought a merlin, a hose reel from ebay - (that looks like exactly the same one that purefreedom sell on ebay) a few connectors and brackets from the local diy, pump and varistream all the necessary things, but all you are doing is shopping for some one, sticking it in the back of their van, and giving them a ridiculous bill for that.
Its no different from anyone else, except its worse or missing things.
sorry but im out (as the dragons would say).
