"I'm really impressed with the engineering of this product, and I'm a mechanical engineer and a software engineer.I just helped out a customer from Europe (expensive shipping!) by using his referral link when I ordered the basic model, and got free shipping to boot -- not a bad deal!I sure wouldn't mind if someone else used my referral link! Thanks!http://glowforge.com/referred/?kid=1ot6VUSincerely,Will"
