Most case reviews I have ever seen are on individual cases, not like a buyers guide with a bunch of them all reviewed at once. If I were you I would look at some vendors (directron, amamax, any others you find on pricewatch), make a list of ones in your price range, then do some searches on things like "<casename>" "review" and see what you come up with.
Speaking for myself, I would not skimp too much on a case because it's one of those things you can't really just replace. Decide what your needs are and go from there. Someone who's into case mods and overclocking may have different needs than someone like me who's pretty hamfisted and just needs a case that I can get around in easily.
Everybody's "safe, cheap bet" seems to be the enlight 7237. Antec's are safe bets too. Remember shipping alone will be a lot ($15-$30) if you get it online. You can buy Antec KS282s at Best Buy and CompUSA for about $60, I think. The SX-830 is about $75 or $80. You might get lucky and get a decent case with a decent power supply for less than $50, but I doubt it.
You can probably save yourself a lot of time by going to your local superstore (if you have one) and just pick one from what they have there. There's also ebay, but shipping will still add a lot to the price.
I have an antec SX830 with an enermax 350w ps. Cost me $117 delivered from Directron. Also check out bestbuy.com. I think the shipping is fairly cheap, although the prices are not the greatest.
