1/2 NL winrates?

[celiboy]

I searched for this, but don't see anything anywhere on expected winrate at live 1/2NL even though I'm sure it's been debated before. I've pretty much stopped playing online due to the difficulty of moving $ around and the death of bonuses. Would $15 per hour after accounting for rake, tips, etc be a reasonable target for 1/2NL or is that abit too high? I've never played live, but there are a couple casinos nearby that I'd like to try out if it's worth my while.
