Dave, I delayed entry into the 2.4 field, too. eventually, I gave in, purchasing a Hitec Aurora 9.
I really like 2.4. There's not much to learn.
After a couple years, I had converted all my models to 2.4 and gave my 72MHz radio away.
If you go that route, I suggest that you choose a radio that has mult-model memory, as you, too, may find that you'll want to convert all of your models over to it.
