The edutools site is pretty good, but remember to add in the new stuff in 1.5.
Also add in what you could do with the license money.IMO
, the biggest thing missing in LMS decisions is support: you can get a bunch of fancy features but few of your faculty will use them without adequate support and training.
If you are going to pay $60,000 to $150,000 for an LMS, IMO get much more 'bang for your buck' if you put that $ into help desk and course designers, and use a free system, as even if it lacks features you'll get maximum usage out of the features it has (though of course Moodle 1.5 hardly lacks features compared to BB 6.2 or WebCT Vista
The Blackboard vs. Moodle
study also has some good info.with comparisons (though of student opinions and grades rather than features) and note that Dr. Munoz and Joan won
Blackboard's BBionic prize for the BB version of the course.
