I had a m8 back in 2003 which then it was the best. I bought another one and Im runnnig it now (got out of racng for 7yrs...lol) The only radios ill buy is airtronics because they are better, faster, more features, and hardly anyone hates their radio that is made by airtronics. O its top heavy yes it is to some extent but the features and reliability more than make up for this. I love my m8 and have held the m11x and love that as well. Once you go thru the features and get an idea it will be a snap unlike other radios where its hard to go thru them all.
