HEROES DIE and to a lesser extent, BLADE OF TYSHALLE by Matthew Woodring Stover.
It's not purely first person present, there's some third person limited in them too, but it pulls it off well.
Present tense is great done well. Especially for stories that rely on suspense and tension, and especially especially in first person stories. It just gives you the sense that anything could happen. If you're writing first person, if it's present we have no idea what can happen; if you don't write in present, then we know that the person's survived. You'd be an idiot to write in past tense with it in first person only to have the narrator die. It wouldn't make any sense, unless the person's dead ghost is telling the story.
I don't think that present tense is awkward, I just think it's difficult to write for first-time writers, and they wind up schlopping off blame, deciding that there's just something wrong with writing that way, rather than simply owning up to the fact that it's probably just them who can't write that way.
