I used to lean my full carboy by using the handle and then reach under it with my other hand. Then I would carry it about eighty feet to my fermentation chamber using the "beer love" method described earlier, dodging corners, steps, and doorknobs the whole way. After reading the horror stories on here about carboy accidents, every step of those journeys were fraught with thoughts of carboy explosion and daggers of wort soaked glass shredding into my unprotected gut.
Now, I have milk crates and carboy crates, that I got from the bottled water delivery guy. The carboy crates are molded the fit the carboy snugly, and can be stacked with the empty carboys inside. The drawback is they will only fit certain size carboys. I like the milk crates, but they take up extra storage space.
I do own one Better Bottle but, I don't use it as my go to fermenter. I like to scrub things, If I can't scrub it, I don't feel like it is clean. I guess it's a little OCD, but for that reason, the Better Bottle is usually the last one to be used. And of course, I haven't broken any of the glass ones yet so...
Edit: I'm glad that you weren't seriously hurt. Five gallons of beer and a broken twenty dollar jug is a lot less misery than a trip to the ER.
