How hard is it to find a grey suit!?

I pondered this question Thursday as we went from store to store looking for something reasonable. One you'd think it wouldn't be that hard to find a grey suit and two you'd think my soon to be wouldn't be so picky. For all of the choices we've made so far you'd think this would be a cake walk. We looked online and in stores looking for grey/brown suits that the guys can buy and not break the bank or as my soon to be says "won't cost more than a car" (an exaggeration I know). Well the search continues... How did you find your grooms attire? Have any advice for me?
