Already August and I've only contributed 2,400 to the IRA for 2007 and that included several purchases beside DCA plus a 1,000 initial investment at the beginning of the year. At this rate I'll end up contributing most of the fund at the end, negating the benefit that the year may have brought. So I decided to bump it up to 100 biweekly. The maximize option would have been better, but I can't afford that right now.
