WD, I did that twice last week, and it will definitely be worth the $15-$20 wire fee.
Don't know if you noticed, but the Scottrade bank is in Missouri, and it took a little over 2 hours to hit my account, going in the morning, and 3 hours when I wired at lunchtime.
I go by a local ST office and, if I get there in the morning, I can trade that afternoon...might save you the $20+ in wiring fees if you have a local office near you.
