New member here, I really appreciate all the very informative information. Just wish maybe i had found this forum before I ordered the Mt. Vernon AE. From the info read: Earlier versions had ignitor issues and control boards issues. I am wondering if anyone that has recently purchased can confirm the issues are resolved. I really could care less for all the bells & whistles like auto clean. But, My wife loves the looks of the Mahogany. I want a reliable model that if properly maintained will last for years. They don't install until the 27th. I may be able to switch to the Enviro M55 if others recommend. Any feedback would be much appreciated.
