I bought the Ikea Expedit 4x2 unit at $99.95--based on what I read here--and couldn't be more pleased for the functionality, price, and appearance. My wife wanted me to go get one or two more! I can see where if you get a bigger unit you would want to brace the back, but the 2x4 is stable enough.
Best part is I play more of my jazz records now because they're more accessible than they were on a low, 2-shelf bookcase that barely left enough vertical space to get the LPs in and out.
