I have the manual crank reel from HF and have had it for 5-10 years. It leaks a bit in a certain position but not others. That doesn't affect it's usefulness to me. I have about 75 foot of hose on it, I can reach the cars in the driveway with the compressor at the back of the shop. It takes a few seconds to reel the hose back in but much of that is spent getting the hose off things.
Somebody over at BT3central bought one of the HF retracting reels to replace one like I have. He mounted it in the ceiling. I thought that was interesting. Gets it out of the way.
I have tools from a lot of suppliers but more inexpensive than expensive. Probably the most expensive tool I have is my DeWalt tracksaw that cost about $600 with two tracks. I have a Ryobi table saw (a BT3100), a Ryobi motor in my router table (R500), Ryobi 18V cordless tools, and a Ryobi radial arm saw. I really like the table saw, the other stuff works OK. I also have PC routers (2 690 motors and 4 bases), a Hitachi dual bevel 12 inch CMS and other stuff. I also buy HF tools for things I don't use a lot. Almost all have been worth the money and several worth considerably more than they cost. For instance, I have a rather large HF hammer drill/demolition hammer. It cost less than $100 and will do the work of ones that cost several times that. Switch that moves between modes sticks sometimes but I can live with that for an occasional use tool. My son got me their 18V impact wrench. It was extremely handy when we replaced floats on the dock and I've used it some since. Ni Cad batterys work surprisingly well. I bought an angle drill from them, however, that is junk at this point. But I got significant use out of it and I think it was something like $25. I carry a tool roll of HF wrenches, sockets, etc. in the back of my BMW. I wouldn't want to equip a shop with nothing but HF tools. I think one could and still do good work but you would also end up messing with the tools to get good accuracy. But the cost is low enough that will be tolerable for some.
