I put an older one in Port Fairy for some cool older dudes ( Mum and Dad) It was a freeby when I made my offices. It died a few years later. The new one is much better Mick. Less gas, heats up much better and much quieter to boot.
Find out what size you need, buy it from the cheapest then pay the plumber to connect it. Takes about an hour tops assuming your ducking is in good nick.
I think I picked up the second unit for about 1200-1500 in melb after shopping around a bit.
