Prompt [Q] Which Phone Is Best For Dosbox Turbo/Qemu?

Hello XDA!
I am an iOS geek, but I am sort of tired of it because the newer devices are very expensive and you can't jailbreak them. The only reason I still have my iPod Touch is because I can run Dosbox on it. I want to get an Android phone that can run Dosbox Turbo (and Half Life on it) and Qemu and other emulators. Which phone is powerful enough to get me at least 10-20 FPS on Windows 98 with Half Life on Dosbox Turbo? My budget is <$200, but I can buy used phones on CraigsList, and I can get some phones for a lot cheaper.

Thank you!
