Thanks for the reaction, sly.
I've thought about the option of buying one. But I've heard it's not really easy to buy one in the US if you're a foreign visitor for two months. Especially the insurance is a problem (you need to give an adress). Can anyone back this story?
I don't really have the money to buy one (even a crappy one) either. I think I can spent maximum 2500 - 3000 dollar.
