This is the closest - mine has braided hose
I think surface postage was about AU$25-30

Works well though I think it would work faster if I was able to set up a better connection to my kitchen tap (but that's another story). It's well made and the connections between the hose and the copper are good.
What I liked about this one was that most of the coils are concentrated up at the top - good given that the heat in your kettle rises. I've used it about 8 times - no problems so far.
I found that I could purchase this and have it shipped from the US for less than an off the shelf equivalent in Australia. I think you'll save money making one yourself (and then there's the 6 week wait for surface mail). However if you want to get something ready made - B3 make good gear. (I also have one of their SS false bottoms.)
(I wonder how much faster a 50 foot chiller would work - or whether it would mainly be of use for large batches?)
Another option is a counterflow chiller. From what I've read the convoluted chiller from St' pats get's good feed back, along with the chillzilla

From what I've read they're almost identical, yet the St Pats is about US30 dollars cheaper.
I understand that counterflow chillers work faster than immersion chillers and can also be attached to a hop back - can also do other things like fitting inline aerators - eg. pumping from kettle to counterflow (which has a link to an oxygenator) to fermenter.
Like immersion chillers, you can make a counterflow - either from scratch or using a kit like Phil's Fittings (available eg. from Grain and Grape in Victoria)
