web based assigning software

[mach3]

Hi,

I am looking for your experiance w/ web based assigning software and contact details for the companies that offer them.

It does not matter if your experiance is from the side of the assignor or from the official using it. I would be interested in both sides. Was it easy to use? Did it save you time? Money? What size of association did you use it for (number of officials / number of games)?

Which one is the most recommended one?

Thanks for your input.
