We are in the process of purchasing (3) 9x7 garage doors / replacements. Both guys are real nice both are using the Liftmaster...Here is the question. Amarr Designers Choice is the appearance I want and the mechanics/construction my DH thinks we need. (we have alot of skate boards, LAX balls etc so denting is a concern) On the other side of the coin is the Wayne Dalton 8300 series which is pretty close in appearance and the cost is great. Is one door far superior in construction or are they pretty silimar? Any input is greatly appreciated. We live in the Ct so we get a fair share of cold nights.
