Definetly check boxerrebound.com I am trying to convince my wife to schedule a day to look at one. I drove 4 hours one way to St Louis, MO for Attila, and that was the best day of my life besides getting married. The third best day was getting Daphne, and the 4th best day was getting Ramsey, but one of the worst days was giving Ramsey to my wifes boss.
Just make sure if you go through a breeder find out as much as you can. Just right across the street from my house is a BYB for boxers, huskies, and bull mastiffs. Her female boxer is CKC registered but selling the pups as AKC. I have called the local animal control numerous times for their dogs running loose down the street. She also breeds her constantly and I feel sorry for that female. She is 3 yrs old I believe and has had 4 liters, with the last litter having 11 puppies. She keeps asking to breed with Attila but I keep telling her I dont think so! We have had about 10-15 people ask to breed with Attila but we keep saying no. We would get him fixed but in our purchasing contract it states that they want him back at 1.5 yrs old to see if he meets their breeding standards.
I went way off subject...but just remember you can find beautifull boxers that will love you the same at a breeder or at rescue. You can also check petfinder.com boxerrebound.com or any other boxer rescue. I even thought about driving from Illinois to Ohio if the rescue would allow me to adopt that far awa.
