Road Trip!!
I've never had to deal with Harman so I don't know about their customer service although I've heard it's less then stellar. I can tell you that Alaska has good customer service and LL has incredible customer serivce. I've yet to deal with anyone that is as knowlegeable and as helpful as Jerry from LL. Also, the Coaltrol is a fantastic product so keep in mind if you buy an Alaska you'll probably end up spending another 350.00 to get one. And I didnt think you were bashing the MFG. in any way but being honest about your travels.
