But, a lot of older machines DO have very nice resolvers integrated in ways that make them difficult to replace with modern encoders. That is the only reason to use them, as you can get very good new encoders at reasonable prices, and use the signals directly. There's no way a resolver PLUS a converter board will ever be that cheap. But, if it involves major surgery to replace a deeply integrated resolver, then it might be reasonable.
$13/100 scares you? I'm stuck using $35 FPGAs until I get a new version of one of my boarda working.
