Sink upgrade - single sink double wide...any cons?
Having done this same thing myself a couple years ago, I think the only real downside is not having a built-in divider. And, for me, it's not really that much of a downside. Some people like the divider, since it helps with dishes (you have a wash side and a rinse side), or helps organize dirty dishes. I like having the extra space, and the double-wide single-basin sink allows me to wash bigger pots and pans more easily.

With a single basin, if the drain clogs you're out of luck until you fix it. Or if the disposal leaks. At least with two basins, you could use the other basin until you fix it, assuming the clog isn't past the junction of the two. Unless you clog drains often, though, this is really a non-issue.
