My take would be to learn with the racket you have, then if you decide that tennis is for for you, then you might want to consider upgrading. I'd hate to advise you to buy an expensive racket and then have you decide that you don't want to keep playing. That's what I did waaaay back when. I bought some kmart special racket for about $5 and after I fell in love with the game upgraded to a nice model (the ole small-headed Head Pro).
