enco rotary table price

Im in the market for a 10-12" rotary table, and while I was at a local machine and tool supply house, I noticed a brand new, but older, Enco 12" H/V rotary table. The tag on the table said $600. The owner noticed my interest, and struck up a conversation, long story short, they said they"d take $300 for it because they had it for about 15 years now and really need to clear out some inventory. It says made in Taiwan, and it turns very smooth, and generally looks good, but there is a lot of backlash, but the handle felt like it had some loose bolts. What Im wondering:

3. What should I do to check out the accuracy of it? Can I put a mag-base dial indicator on the table base and spin the table to check flatness and runout?

I have an eight inch that I ordered from Enco but it looks different (has two vertical mounting lugs and two horizontal lugs). Mine also came with the dividing apparatus and a 17 - 47 hole set of plates. It IS very heavy, as you mentioned, and I have made a small roll-around platform for mine so that I can move it around the bench during setup. I"m considering a crane to move mine, too, but in the meantime, here"s what I do:

After I get the table set up to my liking, I lower the mill table so that it is an inch or two lower than my workbench. Placing a plywood ramp between the workbench and the mill table, I roll the rotab down to the mill and carefully slide it off the little wheeled platform onto the table. To get it back on the workbench, reverse the process only raising the mill table an inch or two above workbench level.

Mine hasn"t seen extensive use but works well ... I"ve made a couple of large milling cutters from 1-1/2 diameter drill rod and a number of smaller projects. (I even used it for a couple of woodworking projects with my home-made router spindle attached to the mill quill.) The cool thing about it is that the backlash in the worm can be completely adjusted out. Frankly, I"ve thought about a smaller table (for convenience) but the argument for the bigger table is that more mass prevents chatter and makes for a smoother cut. If yours doesn"t come with dividing plates, you might consider that as one of your first projects.
