Snow.......without a doubt several folks are going to respond to your post by encouraging you to go for it, based on their experience with the 99/500 card. In advance, I will respectfully disagree.
Your scores are fairly decent. Too good to even consider a secured (or partially secure) card. With a 681 EQ you will be able to get a failrly good cl from most CU's. MOst CU's pull EQ, exclusively. I would also venture to say Chase and/or WAMU would approve you with your current EX score.. My sister was recently approved by WAMU for 4500 with a 642 EX.
So.....before spending $$ for a secured card, I'd look elsewhere first.
to app boa with a bk and get the 99/500 is a nice oppurnity if you want boa. the card will graduate to unsecured with good behavior. i think boa is among the top prime lenders, preferable to chase or citi IMO.
