btw, Its a good price for the game... but you WILL remove 90% of it.
If you aren't going to use the original monitor, it's not worth it for you (probably).
for 350 bucks you can make your own 100% if you have most of the tools. Then it will be yours. But you will have to find a monitor somehow.
but what I would do (if I could do it again).
1) buy the cab. make sure the monitor works well.
2) buy a jpac. This takes care of ALL your connections
3) buy a trident blade video card (or any of the others that work well with an arcade monitor).
done!
plus I would add another interface between the original board and the extra - non jamma connectors... then also do the same connector between your jpac and the buttons 4-6 for SF.
Why? Then you can plug in your original game and other jamma games easily. Why? They are SO cheap on ebay now, you might want to make it so you can play the originals of a ton of games... They are better that way! (mame is great, but there is a difference... mainly in the visuals, but it's still there). Great also for your favorite 3d games that aren't supported anyway now.
good luck
