Daro, great, fantastic! Just like you, because of the price, I've been thinking that the best way to have this would be to make it yourself. The only drawback for me is I'd need to buy a pipe bender, but that I would have more uses for later. The main drawback for me is the welding part, which would need to be taken to a shop and we all know how much they charge.
Great photos and walk through!
