I have appreciated going through this thread, I have the money and am ready to replace my old worn out factory HU. I too have been trying to decide on the eonon GA5150 or the Avant II. I wish you had it in your car now! I think deep down I prefer the Avin, but the cost of the thing just scares me. I'll be getting one or the other by the end of this week. Can you tell me what it boiled down to for you and why you chose the avant 2? I've never actually thought of sending Tommy a message and let him know what I'm going through, I may try that as well. Cheers!
