Thanks so much for all of your thoughts and opinions! You've all been very helpful and I really appreciate it.
We were supposed to shop for rings on Saturday but it didn't work out because we got to the jewelers a half hour after the store had closed. It sucks because it will be two weeks before we will get a chance to go again and it's not like we've got a whole lot of time before we get married!
I did try on a channel set band a month or so ago and I thought it was alright. I was at a mall jewelry store and they didn't have a very big selection. They didn't have anything like the first two pictures I posted. My biggest concerns are durablility and comfort. I know that I definitely don't want a full eternity band because I think that would be very uncomfortable; ideally, I think I'd like a half eternity. As for durability, I am afraid that I'd knock a diamond out of one of the pave bands.
