$500 was a steal for that! I have a SSK4 that I got on ebay I think for $600-700 or so. It had never been used! I was happy about that score. I wish I could do 8 reels at a time. I asked Phototherm about what it would take to convert from ssk4 to 8 but never heard back. I bet it's just the drum and new programming.
I bought the 4x5 holder too (ouch that is pricey!). I wish it could do 8 sheets at a time instead of 4 but ah well.
