Gamertag for Xbox 360?

Hey, I'm getting the new 60GB Xbox 360 Pro 2008 Holiday bundle tommorow for my Birthday along with the wireless adapter and I'm getting xbox live. So I'm wondering what should my Gamertag be? I was hoping for something like Bacher94. My last name is Melenbacher (Funky German name I know lol). Its pronounced "Melon-Bock-er" not "Melon-bach-er). So I'm afraid people are going to pronounce it Bacher instead of Bocker. I was hoping for something around Bacher94. So any suggestions?
