That table brings back fond memories. I bought one in the late 80s, the IIXE version as I recall. While considered a mid tier table, it was remarkably good for what it cost. I think they were around $450 then. The table has a sprung suspension that is fairly easy to tune. The glass platter has quite a bit of mass, and I used a Platter Matter mat instead of the felt one. The Profile II arm was really quite good given its modest cost. I used a Sumiko Alchemist IIS moving coil on it, and that cartridge cost as much as the table did.
There were later upgrades for it, such as an acrylic platter, aluminum arm boards, and electronic speed controls. The interesting thing is Audionote is reported to have bought the rights to it and used this design as the basis for their first generation of tables.
I always thought the Systemdeck could be improved upon, and I sold it when a friend offered me his Sonegraphe SG3 with Sumiko MMT arm. To be honest, I always thought the Systemdeck sounded better than the CJ version of that table. If I ever needed a good modestly priced table, I would grab one. Actually I have had to restrain myself from buying one several times. This one is the spitting image of the one I had. Good memories.
