Rough estimate of the going rate of carts....
SS2 home cart - $60
Metal Slug MVS - $60
Conversion Labor - $70
So, about $190 for a Metal Slug. You can find the MS and SS2 cart cheaper, I was just using the higher end prices in the example. You canfind SS2s for about $40 and MS for about $45 if you look long and hard enough..
