There aren't that many that "guarantee" admissions to an allo school. The best ones you have are the ones at Cincinnati and Toledo and Georgetown that might guarantee you an interview if you perform at certain expectations. It'll drastically improve your chances of getting in at the host institution, but I think the ones that guarantee an admissions are mostly post-bac programs where you haven't taken any pre-requisite classes yet. If you want to find out which SMP have guaranteed acceptances, scroll down the forum thread and look in the "post-baccalaureate" section.
