I'm planning on installing an ArcadeSD board, they have been out for a year or so, and were made by some guys who are well regarded in the arcade world, they recreate the games as faithfully as possible to the originals and update the board every three months, updating is as easy as installing the update with the ROMs which are inserted into the board via an SD card. They apparently are far superior to the Chinese 60-in-1 boards, no lag, correct sounds and the ability to save hi-scores etc.
