If you get the MiniMig, be sure to get the 4 MiB version. It's well worth it.
RE:Official OS
OS 4 only works on PPC AmigaOne systems. It won't run the old games without an emulator. IMHO, you're better off with an A1200 or one of the FPGA-based options if you want to run old games.

Oh, I see you know that already. FWIW, a lot of people reject the "official" solutions and use other hardware platforms to run software on. I'm rather fond of AROS since it runs most of the software that's worth running on OS 4 but it can run on generic Intel-based hardware. Also MorphOS is an excellent example of PPC Amiga-ness on old Mac hardware. For the most cost-effective Amiga-like experience, I'd recommend MorphOS or AROS over AmigaOS 4.x at this time.
