2nd Body choice?

Hi guys

Need your advice again? Recently you convinced me to go for 600D with 18-55 and 55-250 lens. Well, maybe not directly, but asking a few questions on the forums and following various threads, it did not take a lot of convincing from the shop owner's side to have me settled on the above combo deal.

Well, you have created some marriage tension in my life. Me and my husband both really enjoy the camera, but now have to make turns. It sometimes becomes frustrating. So, after deep thougt and consideration, the answer came to me. We need a second body.

Which one? Another 600D kit, 60D body? With budget more or less in the region of 600D kit, what would you have done. My thinking was a body with different E-FS lens? Worth waiting for 700D?

Your opinions?
