I've got the Coleman and am vary happy with them. They were easy to put together although it takes a little time.
Whats nice is the feet are adjustable. My floor has a pitch and I was able to adjust the feet on the three sections that have my work table on top to level it all out. The ones that mount on the wall are super easy to set up also.
On a side note, I took an extra step and sealed the bottom of the drawers so fluid wouldn't damage the particle board (or what ever it is). I also used wood glue on all the screws, these things are solid!
Good luck and post some pics of that floor when the dude is done.
