I found a used 9 tray Excalibur on Ebay. It looks brand new and works great. I just looked and there are several used ones for less than $100 on Ebay right now. Good luck!

Yeah, I got a baby 4 tray Excalibur off ebay and it was a bargin. (Can't remeber exact price now tho)
Worth checking out as they are good.
