I don't think that you can repair these ones either. I had a Frankenstein machine and the large display in that had the sticky ribbon cable instead of actual metal pins that can be re-soldered in place.
About the cheapest place I have seen these display is Mad Amusements but you are probably still looking at $400-500 by the time you get it here. Unfortunately it is one reason why people shy away from these Sega machines, if the display dies there doesn't seem to be a cheap fix. My deisplay when I replaced it cost me well over $500 landed but the dollar was nowhere near as good then.
