Clip together floating floors can be purchased from Ikea, Bunnings or carpet shops from about $16.50 per metre. Check the durability rating. Go for heavy duty residential as a minimum.
Carpet can be depreciated over 10 years where floating floors is 15 years.
You can easily lay floating floors yourself. All you need is a drop saw. Make sure you leave a large gap (15mm) around the edges to accomodate swelling/shrinking. It's best to remove the old skirting boards and install new thick ones over the floating floor.
I think they are great. Much easier to clean than carpet and look pretty fancy. Just make sure you install them properly. Keep a few spare ones so if any get damaged you can replace them with the original.
