Xevious is also one of those games that virtually no one likes. I'd be willing to bet that there are way more Xevious cabs than there are people looking for one. This drives prices down which makes it a good candidate for conversion. At least after you convert it you have a chance of selling it...
Converting a Gyruss blows my mind though. Many people are looking for it and the CP is in an awkward position for playing games with more than one button.

Also true. I used to have an Xevious that was immaculate, with maybe 5000 total plays. Physically and electronically original 100%, almost no flaws. Bought and sold for $150.
