What will you be using it for? Strictly boxing rounds or other workouts as well? Also, are you gonna be using the same amount of time each time you work out or are you gonna be varying things a lot? If you're gonna be doing really simple workouts, like say 3 minute rounds 1 minute rest all the time, I would make on myself with an mp3 player. I actually have that cheapy yellow Everlast timer, and it's ok, not very loud tho, so you either have to have it on you with the vibrate, which is ok, or sitting somewhere fairly close. Not bad for the price.
