I have the bottle tree that fits 90 bottles, with the vinator that sits on top. I will say that it is wonderful!
Like most of the others here I rinse my bottles out directly after pouring a beer. I usually wait till I have about 2 cases saved up then run them through the dishwasher to have a hot bath and dry.
On bottle day, I break out the bottle tree and put a little bit of sanitizer in the vinator. Get all of my bottles out and start the sanitizing process, doing this while heating the priming sugar cuts a bit of time off. Not to mention that it is easy to grab a bottle of the tree and fill it once you have them all sanitized!
