1st NYC Travel Assignment--How's my pay?

I'm new to travel nursing and wanted out of my permanent job so very badly that I didn't particularly negotiate my contract. I basically just said "yes, yes, I'll take it!". All I was really looking for was a lateral move from a financial standpoint, and was really after a new (and hopefully better) work environment, learning new things and growing as a professional. Don't mock me! I really mean that! I was scared of staying at my first nursing job forever (five years was plenty) so I vamoosed and headed for traveling.

I was so pleased with the idea of basically making the same hourly wage and having to *not* deal with unit politics that I didn't think "hmmm...maybe I'm worth more than what they're offering me."

I make $29/hr with a $2200/mo tax-free housing stipend. I found my own housing (I'm very familiar with NYC). My healthcare package is something like $225/mo and is fairly comprehensive although my med copays stink. Luckily I'm not on any meds! While the money is fine, I'm wondering (because, well, duh) if I could or should be making more. I already extended the contract because I really like the hospital, but the next time I extend (if that's an option) I'm wondering where my wiggle room is. There are several travel nurses on my unit-- from several different companies--and they all seem to work perks into their contracts. One doesn't work weekends, one works a week off into every contract etc etc. I don't have the stones to ask what they're making.

Any travelers out there in NYC with some hard numbers? Oodles of experience? Advice? Questions, comments concerns?
