Those nickles and dimes ad up quick. After 3 weeks with the T Rex. haven't spent a dime. (knock on wood). I'm just learning the machine its so quick it will scare you but treat it with respect and you'll learn so much more than with the Pro. I'm still waiting to hear how the HHKII pans out I still need something to play with around the house. I'm so impresssed with the Align stuff I'm looking at the 600.(God help me)
