Automated test lead switcher?

We run Met/Cal and if I had a way of automatically switching test leads, I could make a few procedures completely automated and make a few others a bit quicker. I know of a modular data logger that can do it, but it does a lot more things than we need and seems overkill for the task. I suppose it might not be terribly difficult to make something, but I've got more money than time at my disposal, so I'd prefer to make something tried and tested.
