Where is over here? If it's in the US, TennisChick gave you the link to TennisWarehouse and they have a demo program where they'll ship rackets to you. It might seem a bit expensive (about $30 for two rackets, I think)...but when you're looking to spend $200+...it's well worth the investment. Dick's Sporting Goods is also a big box retailer that has demos too.
Still use your local shop as a resource. And ask, you might be surprised at what they're willing to do for a new customer.
