My brother-in-law is up for a major anniversary. He runs a carpenter/bulding construction company, so spends a lot of time eiher in his van or at sites. He is also a big Howard Stern fan.

So based on that, the perfect gift would be a portable Sirius box. But I have no experience whatsoever of Sirius, so do you have any recommendations/warnings/advice? Which unit would be the best?
