Thunderbird Sport 900 Paddock Stands

Due to the expense, and lack of availability, of centrestand kits what do you use to stand your bike up. I have a front wheel chock, which is great for washing and working on the bike. But, and it's quite a big but, the rear wheel stays on the ground. This makes chain maintenance a pain. So, the obvious answer is a paddock stand, but which one? There are hundreds if not thousands available on Ebay/Amazon. What are you guys using, any recommendations, good ones, bad ones?
