I hear guys talking about slingboxes and watching their home DVR while on an international layover. I'm looking to buy one and I'm looking for any advice/info that may be helpful. Where is the best place to buy one? How much can I expect to pay? Is there a service fee or monthly charge? Is one brand better than another? Are there ones with more bells and whistles and is it worth getting the extras? Are they compatable with most laptops?

I have done no research on this yet, but figured this forum was a good place to get feedback from guys who actually use them.

Thanks
