Getting into the Neo-Geo is daunting - three hardware variants to choose from, and even more variations within those parameters to consider. Prices for games across all three main variants are wildly different, and there are no concrete price guides in the modern era due to the volitility of the Neo-Geo market. The Neo-Geo is, for all intents and purposes, a collector only machine these days - even the lower priced variants like the MVS and CD. If you're thinking of getting into the Neo, consider modern emulation or FPGA solutions first. If you simply must have a physical Neo-Geo library, though, this guide will help you decide which variant is right for you.
