I think that Rachals is a pretty decent make - as I recall, the Kaster company's best in-house piano brand (as opposed to pianos they brought in to fit with players). The Autopiano action is a decent one as well.
However, the sad fact is that there is not a great deal of value in these at the moment. A lot of it comes down to general condition. If it's shiny and nice, somebody ought to want it, but not if it's scratched and tatty.
