Bob 56,
Welcome to the hobby. I learned on my Kadet and I still enjoy it almost two years later. As for the radio, I can tell you that my dad has the 6AEX (or whatever the letters are

) and I have the 7CAP. I prefer my 7-channel over the 6AEX (?), not because of one channel, but there are some of the programs where I can adjust my radio but my dad's doesn't have that capability. Maybe I'm just used to my radio but it seems a little easier to do what you want to do. My opinion. Now, waiting for (or getting a current) 2.4 system does make sense to me. If you could borrow an old transmitter until you find your own 2.4, I think you would be further ahead. Heck, I've got an old Futaba Tx that I used on my Senior that I'd give you for the cost of shipping if it would help you out. It does have provisions for a buddy box but I'll have to look and see what the model is. If you're interested, I'll find out more.
