I currently have an OEM Sirius in my car, but would also like to have Sirius radio at home and on my motorcycle (and, potentially my other car as well). Which portable would work best primarily for a motorcycle, but also could be used with home stereo (think poolside music!)? I was thinking the Stiletto 2, but is that overkill for on the motorcycle? What about the Starmate or the Sportster? Think about how on a bike, you don't have a lot of need for bells and whistles, as long as you can plug in headphones and mash the keypads with fat fingers in gloves.
