Assignment Software/Internet Service

[canuckref]

Great list. I am very interested in starting to use one of these systems. Could someone provide some objective feedback on the pros and cons of some of the systems they have used. I looked at all of them ...some seem very badly designed, well others seem excellent. It is also my experience that a flashy professional looking site does not always equal a good product.

I am looking at a system for assigning refs that uses email and website, has confirmation built in, has ability to deal with cancellations, has the ability to distribute games evenly among levels of refs and is easy to use. Please indicate costs of systems if you know them, that is a big consideration.
