Disappointed with the HTC TOUCH DIAMOND

[Kayoss]

I recently bought a new Sprint Diamond phone and flashed it to my Cricket service. I really thought I would like the touch screen design but instead, found it annoying. When talking on the phone and just simple handling, I would accidentally press the screen, which would activate another program, change a setting or mute the ring or system sounds. Even if I could correct this, I just don't care for the phone.
Can someone suggest a phone with physical keypad and similar functions to the diamond that can be fully flashed to Cricket? I was sorta looking at the TREO 700-800 but haven't really looked into it yet...will hopefully have time later. I was hoping someone might have some input to save me some time searching. Would appreciate it!
