Don't think that rarety and price are always related. Some are rare because very few were build. They are useless unless for collectors who want to have the complete series. Others are rare because they are old or because they have some original features. They could be more expensive for that reason.

For example, the FX-880p is very expensive but it's very common : some workers still use it with old programs.
