Does anyone manufacture an affordable panel sander for the home shop?

I buy a lot of rough cut lumber from local sources, I have a delta planer but when gluing up panels I could use a panel sander. All i've seen so far are made for commercial applications (cabinet makers & such) way beyond a DIY budget. I saw one years ago that used the table saw as a power source but I think it was homemade or maybe a kit? Thanks in advance for your assistance
