The pro Park stands aren't really self centering either. Used TS-6 like above would be ideal for home use. Used Park pro is always a good choice if you can find one.

I think you're better off with the zip tie method illustrated above than a really cheap stand. Zip ties and a dishing gauge... I'm sure there's a home brewed version of the latter.

That said I use a cheap Minoura stand these days - and I take heat from my bike geek friends for doing so. It is floppy and imprecise and not as good as a Park. But it folds away to nothing and is good enough for me. It's the skill, not the stand. Like [MENTION=381793]gugie[/MENTION] I've built hundreds of wheels in bike shops BITD, and spent countless hours in front of a Park pro stand. However for occasional use at home, I don't need that much.
