Let's positive thinking!
I'm not sure of those shielded blankets you mentioned, but building a faraday cage isn't too expensive. I'm not sure I'd bother trying if I hadn't identified the source of the interference and knew it would help. But I guess if you build the cage and it doesn't work, you could always use it to jam any bugs in your apartment. And interfere with your neighbors' cordless phones.
