I have just received my original SD1 back from Daniel having sent it to him to be upgraded to SD2 specs. The original worked great but the SD2 has all sorts of extra bells and whistles. You can find all the info you need on his website
www.slotcardragon.com . There are videos of how the different features work and tech on installation and set up. I'm in Marlborough, MA and his update service is out in Portland, OR the turn around was one week or less. Super service!
I was kind of surprised that no one mentioned Dan's Joe Walsh "Analog Man" reference.
