Thanks for the replies guys.  It would be great if there was a joint that offered custom rom (game) selection into the 60 in 1 boards, just to strip out the few that clients would not like and add a few of the ones that will work etc.

I think I am swaying towards the Hankin clones, purely because of the position of the buttons and joystick.  I'm not 12 anymore and the joystick position on the old Taito's is not ideal.  The Gamemaster clones do look a heavier build though than the game essential ones.

Does anyone have either from these guys at all who can comment?

I have been scouring Ebay and have seen what's available but nothing really pops out and grabs me, hence why I was looking at a new Hankin clone but great quality
