If you're not someone who likes fiddling with hardware (I do!), stick with emulation.
There are some hassles with vintage Amigas: 1] does it come with a compatible monitor or do you have one? 2] are you willing to expand it enough to make it usable (This might include some fast ram, or a hard drive, or some kind of card reader, or a video adapter. Or all these things, depending on your goals.)
Many of us are happy museum keepers.

It sort of takes a critical mass of hardware and software to do more than play games.
