Mif2Go: Frame to DITA

Omni Systems is the developer of Mif2Go, a FrameMaker plugin that outputs DITA (and a dozen other formats). It is free for unemployed and underemployed tech writers and pubs consultants, as well as educational users (students, faculty, and staff), most nonprofits, and FOSS developers and documenters. For commercial use, it is reasonably priced at $295 per seat, with steep discounts starting at five seats. Annual support and all upgrades are included for the first year, and $75/year thereafter.
