Hitting the ball low may be due to other circumstances than the ball. Could be the club, shaft, your swing, etc.
That said, I've been playing the Srixon Q-Star Tour and really like them. A high quality urethane ball for $30 a dozen.
I bought a couple of dozen of these used last year from lostgolfballs.com and the mint condition ones were truly like new. $9 a dozen right now.
