Amazon has the Sunex 10-ton jackstands on sale for 14% (short) to 45% off (tall). I picked up two pair of the tall ones for fab work.
I was a little concerned about how the boxes arrived, but all parts made it with only a bit of scuffing and chipping to the paint. I'm sure I'll do more damage to them in the next couple of months, so I'm not too concerned about that.
These things are solid and heavy. I doubt I'll come anywhere near the capacity of them, but they make a good stable platform to work from.
