J, nice system. What caught my eye was the color on your shelves. Check out my system--it's like we're separated twins or something!
How did you finish the shelves?
Fwiw, I painted mine with enamel (black on some and on others colonial red, I think) and then sanded, then hit it with many coats of clear spray. Then, more sanding. Got down to 1500 grit wet sanding and called it quits. Nice, mirror shine, but the finish is soft and component feet tend to stick. Guess I may just buy my next shelving...
