He's complaining about cost, so a Vampire is not necessarily the best option (euphemism)

A Raspberry Pi 4 with PiMiga is a great way to get your feet wet (and might be all you need eventually)

The Vampire is a proprietary closed-source FPGA core that has nothing to do with the spirit of the Amiga. Their emulated CPU and chipset has glitches and issues are the order of the day.

A miSTer FPGA is a much better option, being completely open. An original Amiga 500 is not crazy expensive yet, and WinUAE is also an option, being the best and most accurate software emulator for the entire range of the Amigas (a lot more accurate and faster than any Vampire).
