Looks like I am the first to post in the T E S O R O forum! I have 3 Tesoro uMax machines and a large assortment of coils. I have tried a few other machines but always go back to the smooth power of a Tesoro. My Tesoro's and I are currently on a VISION QUEST. When my finds add up to enough, I plan on trying out a V3. I will still keep the Tesoro's around to keep the V3 honest! Happy hunting to all no matter what machine you choose. 8)
