Hi A.! We've finally finished most of our furniture buying, and I empathize completely! One main thing comes into play: will you be having more than one child eventually? If yes, then spending some more money is worth it as you'll be getting your money's worth. There isn't much anywhere that's priced reasonably unless you look for bargains (we got a crib at PotteryBarn kids for 200$ off because they were having a sale and the color was a discontinued one).
We got the most help from a book called Baby Bargains--it gives reviews and is very up-to-date, and also tells you what not to waste your money on. Since we are only having one, we bought a changing table at Ikea for 145$--when we're done needing it for changing it'll be turned into a storage cabinet and it will probably have made it's money back (i.e., it'll last for about 2 years, look okay while it's doing that duty--then go on a porch or in a pantry to store towels and cleaning supplies, etc.).
If you're planning on more than one child, I would look at places like Pottery Barn Kids, Land of Nod--especially if you're trying not to overspend but still want furniture that will last. Whatever you do, skip the changing table and go for a dresser with a changing top--that way you have a nice dresser when all is said and done!
