Downloads, usb drives, DVD’s – your thoughts?

Hey, we are thinking about offering downloads and/or offering usb drives of recorded shows. Would like to hear peoples’ opinion. Would you be inclined to pay a bit more (let’s say $10 instead of $5) to be able to download a show? And would you be willing to part with $20 to buy a USB drive with the show on it (at the show )? We could also do DVD’s and/or Blu-Ray but those would have to be at least $30 and delivered later, and besides it seems like it’s a dying technology – I haven’t played a DVD in over a year. Would love to hear GigViz members thoughts on this – what do you think?
