Good luck with you Shopsmith. I have a Chinese knock off Woodmaster and have used it quite a bit. I like it for what it does, but would also like to get a regular table saw as the tilting table really limits it's usefullness. I used to have a radial arm saw and this satisfied most of the angle cut requirements, but that went to my stepson (I got it from my father-in-law, so it should rightly be passed down!).
Mine has cast iron tables so it weighes a bit more than the Shopsmith. I have drawings somewhere for cabinet that goes under the machine if you would like them. You can get replacement way tubes from Shopsmith or lots of times on ebay. Unless you can get the tubes really clean and waxed, the headstock and table mount won't slide easily and it becomes a pain to move them for different setups.
All the best
