Stiletto SL10 vs. SL100

Was thinking about upgrading to a portable Sirius unit, and was wondering if anyone has either of these two radios.  What's the difference between the two?  The only thing I see is that you can only record 10 hours of programming with the SL10 compared to a 100 hours with the SL100.  This isn't a big deal to me b/c I don't download music nor do I plan on recording that many things.  I just want something where I can listen to other games at the stadium or just listening to whatever out and about.  If the recording hours is the only difference, then I'd rather save $100 bucks and go with the SL10.  Also, at their website, it looks as if they are a different shade of black.  Is this the case?  The SL100 is dark black and is very shiny/glossy looking.  But the cheaper SL100 kind of has a faded black look to it.  Are they the same color or not?  Any kind of input would be appreciated.
