I have the BedTred from Bedrug. I initially liked it, but it doesn't stand up to hard use. Mine is torn up from throwing firewood in, dragging furniture across, etc. They do have a warranty, but I'd have to take it apart and mail back the damaged piece (difficult and expensive to ship). I'm a little disappointed that it isn't as tough, especially for $400. My next truck I'll go back to Line-X and maybe put down a rubber bed mat to make it easier on my knees. I've chipped up my Line-X before, but that's easily fixed by taking it back to the installer and having the damaged area re-shot.
If it was $200 I might be okay with the quality... but it costs about as much as a spray in and seems inferior for MY needs. If you are super gentle with it and don't drag things or toss heavy items in, it'll probably be fine.
