1) Hunter Engineering makes that machine. On their website, they list registered locations of the machines. This is a link to the page that searches locations: http://www.gsp9700.com/
2) If all else fails, call Barry at Myers Bros. (816) 931-5501 and ask him where he sold some of his machines.
It really does resolve balance issues. May be pricey but worth it.
Thanks. I posted the question at their site and they gave me the url to the lookup page.
Looks like Bailey Automotive in Olathe has a machine. Pat Bailey did a FANTASTIC job on aligning the Cobra's suspension... I think I'll give him a call.
