I had a FT Sysport but sold it after a few years of use. I found it heavy and the drawers were difficult to release and open. Plus as my collection of Festool expanded, I didn't want to sink more money into more Sysports so I made my own with plywood drawers. In time, Festool released the Sys AZ drawers and I shifted over to those completely - in both upright and under-counter drawers.
I like these much better than the old Sysport. Lighter weight, easier to open and close, and much more flexible. And I'd say less money too.
There have been a couple of older style Sysports for sale on the forum through the years, but I don't know that they ever caught on that strongly and thus was the reason for the discontinuation.
