I don't see why the cost of the box is the only consideration, since when you're bottom feeding you're probably only looking at price differences in the range of around 10-15 dollars. I have a Roku box, and with that box you get a fair number of free channels.

I don't want to spend much because my daughter will only be there for probably the next 9 months, and after that who knows what she will need or want. I would love to get an older Roku for between $25-$50, any more than that and it makes more sense to get a new one for $60. Since this is just a gift from me to them, and I just gave them our old TV, which required me to buy a new one for us, I want to spend as little as possible. If I can't get a cheap, under $50 solution, they will probably just have to make do with the Wii.
