this should be in the confessions thread, but my secret geek hobby since I was 9 was Shortwave.
I have mine set up primarily as an alarm clock now, b/c I can't pick up a damn thing where I live (and I hate the giant antenna). I bought my first one at Radio Shack, so I would say the Grundigs are nice: G3/G6. It's too bad they don't sell the old radio shack brand anymore cause that's what I have. Just make sure it's digitally tuned.
I do recommend the clip-on antenna extender, it does work
Enjoy and have patience! You can pick up a tonne of stuff when it's clear out, especially in Winter.
