Excalibur dehydrator?

Anyone have one of these. I'm wanting to get a dehydrator to help with making the jerkey. I have one of the smaller round dehydrators and it does a good job but take a while and it only makes about one baggy worth of jerkey at a time. Was wondering if anyone had the 9 tray excalibur and wanted to know if it did a good job or not. And wanted to know if it was worth it. I know Cableas has it for like $225 or something like that but I found it on EBay for $190 with free shipping and a 5 year warranty.
Thanks
