Well, this is a delicate problem, indeed. There's not a whole lot of good stands for heavy keys for the standing people.
I've got the black version of the V-Stand (from Ultimate). I find it a bit more elegant than the silver coloured Roland one and as you know it's easy to fold and transport. There's a new Pro version out that has replaced the old one that look nice.

http://www.rolandus.com/products/details/943 One underrated stand from Roland is the KS-12. It also has got three height options but the highest of them is not all that high ... So it depends on your own height. Really fast to set up! Don't know if that is available in the US though.
http://www.roland.com/products/en/KS-12/ Final one from Roland is the KS-J8. I like it a lot but it's really heavy and maybe not as elegant as you would like.
http://www.rolandus.com/products/details/1170 K&M got a couple of options. The first one is not that good looking and it's not really portable.

I'll follow this thread to see what might come up!
