Relative to the 700c tires available, this is true. But by no means are you relegated to choosing between crap and crappier. Search nashbar.com, they usually have a good selection of nice 27" tires. And the 27" Continentals were on sale not too long ago fo less than $10/tire, and they are fantastic all around skins.
