I'm with you on that. I looked at them as well because I'm tired of carrying my chainsaw on the floorboard of my tractor. A few months ago I decided I was going to make one. I thought I'd use some 1/16" steel plate lined with HDPE sheets on the inside to protect the saw. I just never got around to making it but someday I will give it a try. Mentally I got stuck on how I'd anchor the HDPE to the steel. Thought about trying epoxy but wasn't sure it would hold. This thread has got me interested in giving it a try. If I do, I'll report back.That’s my thought as well. If it was $75 I would have one on the way already.
