Here's a couple of pictures I took of the 3520C, I should have taken more closeups of the banjo and tailstock. The guy I talked to thought the price would be around $4250, or roughly $250 more than the 3520B. The locking levers for the tailstock and banjo will be longer than in the picture, and will feature a knob of some shape on the end.
The bed ways are thicker to increase weight, the legs are solid to increase weight, the tool rest lock is more like the 4224B but I don't know if it's exactly the same. The blue LED lights are just for show, and the bed extension is an option like it is now. The doors to open the tailstock storage area and motor belt are held closed with a magnet. The spindle lock is a dial that you turn which is a more positive lock and doesn't require you to hold it in the locked position. I asked the guy if the there is an override to prevent the lathe from being turned on with the spindle lock engaged, but the answer is no. I do like the control box that can be placed anywhere.
