Tormach shows locations of owners that are willing to demo or discuss their machines here:
Mill Demos & Referrals | Tormach LLC | We provide personal small CNC machines, CNC tooling, and many more CNC items
but there doesn't seem to be anybody listed in Atlanta yet. It's worth giving Tormach a call and asking them for local referrals, though. They won't bug you continually or hassle you at all.
