My modest opinion is: you should consider getting an emulator instead, such as WinUAE and/or Amithlon. Performances are far better on a modern PC with an emulator than you would get with an already outdated Amiga.
With WinUAE emulator compatibility issues with games is less problematic than with Amithlon. Amithlon is more suited to serious users who want to do development and other thiings other than playing (old) games with the Amiga.
WinUAE is more suited to general purpose as well as games but can also be used for playing games. Amithlon is also a bit more performing as far as speed is concerned.
So, it's up to you and depends also on what you are planning to do with the Amiga.
Regards.
