The best of both worlds for time management

I am a long-time user and fan of the TimeDesign time management system ever since I attended a class taught by Dave Allen almost 15 years ago. Both the system and Dave blew me away – changed forever how I approached my work. For me the system is a very natural, simple way of dealing with all the “stuff” that gets thrown at you in the course of 24hrs.
There are only 2 things I could wish for to improve it: that the system was less expensive, and it was integrated with Stephen Covey's First Things First system.
Covey’s 7 Habits/First Things approach is important and a perfect complement to Allen and TimeDesign. Covey’s approach is big picture, long-term, "get-the-most-out-of-life” approach while Allen’s is a reality-based approach that says “face the swirling chaos of day-to-day and handle it before it handles you." If there is a product out there that successfully combines the two, I will be it's next customer.
