Picked up the WTS2000L tonight. Very impressed with the quality of it. I bought a Felker FTS-150 a couple years ago and for $600 thought it was very cheaply made. The Ridgid has more like a nice adjustable metal linear guide type slide with sealed roller bearings where as the Felker had nylon rollers on top of a polished shaft. One problem with the Ridgid is that one of my rollers has a flat spot on it which keeps the tray from sliding as smooth as it should. The rollers or anything underneath the table are not shown in the parts diagram. Would I be able to get a replacement roller?
