It's been a while since I had anything new to say on this topic. But, today, I was in our local church charity thrift shop and found a used Fellowes 12 sheet cross cut shredder for only $2.00! Bought it without even trying it out. Got it home, runs as good as new. 
Amazon currently sells this unit (as far as I can tell on the model number) for about $240.00! Everything looks the same as my thrift store model, except this new unit has additional stickers on the top.
I suspect they must have marked this shredder down so much because there was a red blinking light on the top of the shredder - which usually indicates something wrong with the unit. However, I downloaded the owners manual and discovered there was a switch on the side of the unit to flip and the light was reset. No more flashing red light! Good as new!
		
		
	
	
This is my third used shredder currently in use. Over the years, I have worn out a shredder or two and they do break down eventually. So, this shredder will be stored as a backup in case my other shredders die. Well, actually, this is the best shredder I now have so I might put the 8 sheet and 10 sheet shredders in the closet and just use this one until it wears out.
I have about 3 large kitchen garbage bags full of shredded paper to put into the coop. Time to get ready for winter. We have our first winter storm forecasted for this Thursday, so time is running out. Will be taking out the chicken coop shredder paper I used this summer into the chicken run and putting the new shredded paper on the coop floor.
FWIW, I am still very impressed with using paper shreds as coop litter and am to the point where I prefer using paper shreds to wood chips, leaves, etc... that I used in the past. So, I am going to use paper shreds in the coop again this winter.
