As far as a print catalog, Northern Brewer has a good one and the covers are cool.
I think Midwest, Austin Homebrew Supply, and Morebeer are both online only. As far as price and selection, it all depends on where you are at and what sales are going on. There are some related threads on price and shipping from various companies.
Also many smaller LHBS's have an online presence and I'm sure there are some good ones in Ohio.
