I got my new rack & bag put on my bike today. I went with this Topeak set-up:

I was going to go with the basket, to save money, but the LBS ordered me the bag. I was ultimately going to get both, so it wasn't that big of deal to take the bag.

Should work out well for me. Now that my bike is all set up, I'll get a picture & post it on the show your commuter thread.

Thanks for all the help, everyone.
