The shop I used to work at had an excellent one. Similar to the VAR but a better refinement of it I think.
You clamped the steering tube like the var but the bars sliding jig went all the way to the crown so you aligned to the crown first, tightened the steering tube more so it would move in the jig, then checked your blades and dropouts. and aligned those as needed. Used to do a lot of them before lawsuits and when labor was cheaper than a fork.
