Some can be very hard to find. Cantillon and Drie Fonteinen make some excellent sour beers, but they are nearly impossible to find in the US right now.
However, there are other options that are worth looking out for. First and foremost, a word of caution: many fruit "lambics" available in the US are artificially sweetened and not good representations of what a fruit lambic should taste like. Most notable one to avoid Lindemann's, but I would suggest you exercise caution if you choose to seek out fruit lambics.
Now that I've sufficiently trashed Lindemann's, I'll start by recommending the Lindemann's Cuvee Rene gueuze. It is the cheapest and easiest to find gueuze in the US.
Rodenbach, both original and grand cru, are also relatively easy to find and will give you a taste of a different style (Flanders red).
For American examples, Jolly Pumpkin is most widely available. I like Bam Biere, Oro de Calabaza, and La Roja from them. If you're in their distribution area, Russian River is also well known for their -ation line of sour beers (though I'm not sure how easy they are to find).
Other than Russian River, these should be readily available on the shelf of the best beer store in town in most states in the US.
