Yep I have an Excalibur one. Well I have actually had 2 of them, but gave my 9 drawer one to my brother in law and purchased a 5 drawer/tray one instead. they take a lot of room up, but a well worth it. I picked up both of mine 2nd hand off ebay, after some very careful bidding and not going over a self imposed limit. My 2nd one is much quieter than the first one - didn't bother getting one with a timer 2nd time around because I found it unnecessary on the first one.
It can also double as a 'incubator' for proving bread & yeast as well which is handy! Mine is usually one at least once a week for 24-36 hours!
