Racquets for Beginners


I have a couple friends who are just beginning tennis and are looking to buy their first racquets. They are both pretty athletic but with about average strength i guess. They have progressed pretty quickly and are looking to develop more "professional looking" strokes (right now they are dinkballers). What racquets or "spec range" would be good for them?

Right now one is looking at the Agassi LE racquet (i thought it might be too heavy?, lol he claims he wants a unique racquet). What are your opinions on that for him?
