My opinion? I rather get a pin with no displays for way cheaper and pay the 200+$CDN for the Rottendog kit. If there is one part I HATE about early SS pinballs it's dealing with old POS displays.
What never made sense to me was paying 45-50$ for a 30-year-old display on Ebay when a new better display is out there for the same price. Budget permitting, the next pin I do for myself will have all new Rottendog or Pinscore displays. I will sell the old working and tested displays on Ebay and that will pay for the displays directly.
I am even considering doing it for the EK I am doing, strictly for a reliability aspect.
If we were talking about an MPU for a Bally, yeah... it is still cheaper to by an old tested one. But displays... go for new.
Don't the new displays also have the added benefit of not requiring high voltage power? Could save you even more money and grief down the road.

So far I've been able to get all the displays working on my older machines. But I have to admit the Rottendog kit looks really nice and would probably be my first choice for a machine with displays missing.

I agree $200 seems reasonable for the entire package. It would have to be considerably cheaper for me to play around with used ones but I think it's worth a shot.
The HV side to me is no big issue. I have rebuilt HV sections before on various machines. Biggest trick is change everything in the HV section when you do it. The parts to do that is minimal in most cases usually around $10 to $15 bucks, but again factors into your $200 for a complete working solution. Part of it for me is this originality thing. Not that it devalues the machine or anything like that. It's just nostagic for me having these plasma displays working.
