I am now on my third hose for my Q1000.  The first hose, the plastic piece inside deteriorated over the winter, so it needed replacement.  The last two I have had to replace because the squirells in my apartment complex keep eating through the hose.  I love the grill and being able to hook up to a 20 lb cylinder, but I wish Weber would design a more rugged hose, perhaps braided stainless for this grill.  I am currently using camping cylinders on it because I don't wish to spend anymore money on hoses that are going to get chewed threw.
