your best bet would be to get a Square top vendor like a Vendo 56 or Cav 64 or Vendo 63 and then restore it into whatever theme you want.
these machines typically have a light up sign that you could have a sign shop make your graphics, and you could paint up the cabinet in any color scheme you want.
many collectors have made "theme" machines, some sports, other brands, beer, etc... so one of the machines listed above would serve your purpose well and can be found fairly easily for around 300-500.
Thanks but I think I really want that more retro rounded look...
