Open Question: Where can I watch lord of the rings?

I want to watch the lord of the rings movies. I would prefer to see the extended ones but if there is no way I'll settle for the original ones.

I've checked many sites all of them either had it short, required pay or would only allow me to download a file of a certain size and given the length on the movies, it was over the size.

If anyone knows a way I can either download the three or watch them online I would greatly appreciate it. Thanks!
