I probably could have. I'm no woodworker, though, so the thought of having a DIY kit that just requires some 2x4's, a power drill, chop saw, and plywood was very enticing. Usually when I try to tackle woodworking projects, I wind up getting extremely frustrated because I can never get anything square and I'll give up. This kit made it an absolute breeze. Plus, it came with every screw that I needed plus some hangers for tools, extension cords, and hoses. After all was said and done, I think it was worth it - I think if I tried to do it myself, it wouldn't have come out looking half as nice.
As for the manual collection, I don't have much yet. A '92XJ/MJ service manual and a couple of ZJ manuals. Also have a Mopar stroker book and a differential repair book. One day I'll be able to fill the shelf :D
Why don't you skip the paper an just put one flash drive with all the PDFs you would ever want up on the shelf?
You've seen my website collection of FSMs right?
