I have been rocking the HT for many years. It is alearning curve and I have done away with the top filter and use a scotch brite forthe rear. Another learning curve after that to adjust in airflow. My roasts are consistent and awesome. I do have a bean probe in that helps immensely. My son has a Behmor and to me its kinda like driving at midnight without the lights on. To each his own, its about prefernce and product in my book.
