I'm interested -- Hattiesburg, Mississippi, USA
As for how interested? I've only ever gotten to try Blue, Red, and Black Cherry MX switches... and I had to take time out of a Skiing Vacation in Colorado to find a MicroCenter in Denver to do that. From what I can tell no one remotely close to here sells mechanicals apart from maybe a Razer at a Best Buy in another town.
I expect it'll be a while (if ever), but looking forward to it. Brilliant idea dude!
