I'm also cheap - I saved nearly $40 USD over buying new. If they are worn out, or contacts are falling off, I can see replacing - especially at this point, as my pile of junk harnesses is running out of switches to refurbish :)
CV has that weird sling setup with the funky brackets and switches. I've seen some that had micros instead of leaf switches, too. I always look forward to your restoration info and photos, but am really looking forward to seeing the CV. I have one and have sort of a love / hate relationship with it.
I hope IPB makes the playfield this year, though, as it's a beautiful game.
CV playfield was "supposed" to be remade here in Australia 4 years ago - I'll be the first to buy a repro playfield if IPB or CPR make them ! Great News.
