Hey, Jon - congrats!
I wondered how long you'd be able to hold out. Great guitar, huh? You should be covered now, with a big one and a little one. In the words of the philosopher K.C.: "That's the way, uh-huh, uh-huh, I like it..."
After you get to spend more time with the X20, you can start playing the: "I like this one better, because..." game.
The X20 and the X7 should be sold as a set.
