Park obviously makes good stands, for a price.
At the first shop I worked at they bought the bench mount style then had a fab shop weld a pipe to an old tractor trailer rim for a base, then the bench mount holdeer was bolted to the top of that. Saved some $ that way.
I use a portable park stand at home but it moves around, and I'm always on the look out for the shop professional style.
you could try hitting up some local bike shops, see if they have any they are not using..
