GemX http://www.gemx.com is having a 50% off Holiday Sale throught January 20, 2008. I just bought WizQuote for $10.
Looks like they have modularized their do-Organizer since the last time I looked at it. Now you buy the base system (on sale for $12.95) and then purchase the other modules you want - calendar, contacts, journal, etc - separately. The modules are also on sale - priced from $5.95 to $9.95.
Their website says they have a new release of do-Organizer due in January, with updates to TexNotes Pro, SurfGem and Wizquote in the first quarter of 2008.
