afgoody,
I've used Kent for years with good results. I think you'll find others will say the same for Instant Ocean. Dr. Craig Bingman did a wonderful comparative study a few years back of several mixes and posted the results here at reefs.org. Might be of interest to you. Search the board's library and archives for it.

afgoody,
I can't locate the article either :? Anyone else remember the article? I thought it was an article that was on the Aquarium Frontiers index once upon a time. Anyway to access that anymore?
If memory serves, I think Kent and IO topped the list as being closest to natural sea water with regards to % of elements contained.
