This is the one we got: http://www.bunkbedking.com/bunk-beds-bookcase-honey

It took me about 5-6 hours (with breaks) to put together by myself, which seems like a lot but I didn't really mind at all. A considerable amount of that was carefully reading the instructions and diagrams to make sure I was doing it right, which is often not clear. But once it's all assembled it seems pretty sturdy. We'll let you know how it holds up after 6 mos or so. :-)
