Precision table that can move on x,y, and rotation?

Recently missed some very cheap large rotary tables. Accurate to probably +/- 5 arc seconds.

That would be perfect... apart from, i suspect, the market price of such a thing!

I got this one at a garage sale in the mid 1970's. It was actually in the hands of a guy waiting in a que to pay for it. I asked him what he was going to use it for and he said he didn't know, so I offered him $10.oo to let me buy it instead and walk away, which he did.

I have seen them on ebay, so worth keeping a lookout.
