I am and always will be a gigantic fan of ebay. You can get racquets and any type of tennis supplies you need there for amazing prices, priced way below retail. As for which racquet you want is up to you, but since you seem like a pretty "Santoro" like player for lack of a better description I cant really recommend a racquet since I am more of a power baseliner
You could try tenniswarehouse.com to demo racquets, their demo'ing program is pretty amazing and it will give you a few racquets to choose from and play test which will ultimately give you your best fit.
BTW I would never play with fingers hanging off of the racquet, it is probably giving you a really floaty slice instead of a more driving and penetrating slice that is much much better in rallies and on approaches. I hope I helped!
