What about www.boure.com?

Their chamois is very thin, but it might be too wide for you if you're used to tri shorts.

I like their stuff--basic, nothing fancy. The tights are really long, though (something that makes me very, very happy); the knickers seem about average in length.

Oh, and you can get them to make them " just for you ". I buy their shorts, but ask for a longer inseam.
