I'm suspicious of first person books because it's hard to do well and very easy to screw up. I have to trust an author quite a lot, or get some raving recommendations from people whose judgement I trust quite a lot, before I'll buy a first person book. I've enjoyed quite a few of them, and even loved some, but there've been some massive stinkers in that pile too, so I've learned to be wary.

I hardly ever write first person, although I won't say never. My favorite POV as a writer is deep third.
