I didn't realize Harbor Freight had so many bike related items. I guess like a lot of their stuff, it's buyer beware but probably worth checking some of it out. That tool tray looks pretty good, especially for the price.
The best repair investment I have made has been a Park pcs10 repair stand. Can't believe I built up an entire commuter from a ghetto rack bolted to my work bench. It was back breaking. A real repair stand makes all the difference in the world.
