Alternatives to the SHT15 for temp & humidity?

Hello,

I've got an arduino with a Sensitron SHT15 sensor to measure temp and humidity and it appears the humidity reading has crapped out. It reads a relatively constant 72.6% +-0.15% RH regardless of the conditions it is in. I have a control hygrometer to verify this. I'm pissed at spending $40 for a dud sensor. Is there an alternative temp and humidity sensor for the arduino?

Thank you, Jacob

I assumed Sparkfun wouldn't honor that. I bought it on a breakout board and have soldered header pins to it.
