To call this "just a spell checker" is to ignore three quarters of what it can do for you. For me, the Lookup function (highlight a word, hit a keystroke) returns data from it's own data sources along with publicly accessible data is fabulous.

Ever wanted, needed to clean up some text? SCX can do that.

Having troubles? Like detailed below, this program has a very actively involved developer... both in responding to issues as well as advancing the software forward.

Some may get "scared" by the seemingly daunting array of preferences; understand that this is what allows one to very precisely set the software to function the way they want it to; there's no "the developers way or no way" here.

Honestly, this stuff is worth twice what you can get it for.
