From my expierence,Jeff has the best customer servise in the business i have ever delt with.After purchaseing a so called complete cub set up from another builder(not Jim).I had some questions+still needed some parts to make it complete.Jeff is the one who took the time to pick up the phone,answer my questions,get me what i needed+also was a huge help in putting it together+tunning it too.He even followed up about a week later to see if everything was working out.
