I too was somewhat waiting on the rebates, especially for the DA 12-24. I am hoping to acquire it soon before my Navy shipboard cruise for work. However, my wife keeps reminding me that we now have 2 sons in college (1 away and another probably going away to school) and potentially 3 households to support.
Unfortunately neither son is taking a photography class to help me out on my acquisition list - The Pentax Educational rebate.
I think I would tell them that all financial aid always comes with strings attached! :-)
