Today I purchased my first pv, I used a Canadian vendor. I decided on the riva 1100 mAh after reading as much as i could on this forum. I have to say, great customer service and prices! I called Ontario from BC, left a message and he got back to me. Very patient with all my noob questions and even threw in a free Drip tip! I would definitely recommend this vendor to everyone but I don't think I should post any links. So for those who don't know pm me, and thank you Adam! You rock!
