ok thanks for that Jeff, i just wanted to know because they seem like high prices for what they really are.

I was pointed to these the other day: http://cgi.ebay.co.uk/ShuttlePro2-CO...em270288548673

Seems like a better price to me, although a small ali box with everything mounted to it would also do the job, would also be handy for later expansion as well if it was a "home-brew" device.

EDIT: i think kip said he's got one of these, they do a smaller version as well. Here is a vid of this one being used:
