I made my own as well. Probably cost me about $50 in materials. There is an appreciable improvement in the slop of the linkage, and it does move a bit smoother. I think the adjustability is probably the greatest benefit though.
I used Chromoly steel, overkill but whatever. Cut tubes to length, clean up the inside bore to get the threaded insert to fit. Welded the inserts and that's it. Very easy if you have the factory rods to work from as a template of sorts.

I saw that Mary Pozzi made her own, I'm tempted, but for $90 these appear decent.
I have this, replaces the stock rods. I thought it made a nice difference on clutch pedal feel. I'm sure if you have the parts & ability there is not much to it.
