Pretty good price for a Coleman portable hot water system, 50% off retail, but you could usually get it for around $280-$300 previously when on sale. I didn't think to check it out when the ebay 20% off sale was on, may have been cheaper.
It is great for a hot shower whilst camping. I love mine. The only issue I have had is there is no gas relief valve when you turn the unit off, so sometimes it gets a vapour lock and won't restart correctly. If you remember to crack the gas bottle and then run the gas out of it after you finish your shower, it should be fine apparently. I only learnt this after reading up on some forums after my last camping trip.
After looking through the rest of the catalogue, there is a red model now, so the green model has been superseded.
This can probably be combined with the https://www.ozbargain.com.au/node/219923 25% off everything post.
Hope it helps someone!
Just use this and save the $$$.
