Thats fine for truing. And dishing, well just get a dish tool. You don't need a (insert make here) self centering truing stand. Now I'm not found of flipping the wheel in the stand for dishing either but others use it here all the time.
The best looking homemade stand I've seen is this attached one. I was going to make one but I happened to find a good cast iron one for cheap so that's what I use.
