Canada - http://racquetguys.com/ They are an authorized Gamma Distributor, I got their contact straight from Gamma Sports, and made my purchase recently.
Wow that's amazing! I love how you can save profiles, the clamps look super efficient too!! I'm surprised Yonex hasn't done something like this, it seems amazing for commercial use!! My next suggestion would be to tag players racquets with NFC stickers, and the machine can auto-apply profiles!!
