I bought my Neo-Geo MVS cab a few years back for ~$700 - $800 shipped. The one positive, as someone already touched upon is the fact that they use MVS carts and the games can be easily swapped. If you want a Street Fighter game, they have SNK vs. Capcom, plus a slough of other excellent titles, e.g., Metal Slug, Samurai Shodown, Baseball Stars, KoF, etc.
