I've got a Slingbox Pro and it's GREAT! Gotta echo everything FlybyKnight said and emphasize this point; you need to make sure you think through how you're going to set it up and how you're going to use it because it's not as simple as going to BestBuy, purchasing it, then taking it home and setting it up right out of the box. That might work in your case but you really need to look at where everything is in your house/technology sandbox and make sure you've got everything you need there including outlets.

I'm an Apple guy and have had very few problems with my Slingbox and having it go offline except for this past week. For some unknown reason, it went out in the 4th qtr of a game last Saturday at home and I have no one there to reboot it so I was SOL. Then 3 days later, the darn thing started working out of the blue and I've been watching football every night ever since! Go figure!?!?!?!?!

I regularly watch Slingbox on my MacBook Pro and have pretty good reception in most places. Like all things on the 'net though, your results will heavily depend upon your internet connection at your layover hotel. BTW, I also set up my own remote wireless in my hotel room.

Feel free to PM me if you have specific questions and also do indeed check out the competition.

If it's just NFL football you want, you need to check out the NFL Game Pass. That works great and you can probably get a good deal since the season is 1/2 way done.

FYI -- I carry a MacBook Pro on the road, use DISH network at home, and use Time Warner as my ISP.
