Wroclaw is not covered in Rick's Eastern Europe guide. What moderately priced hotels or B&Bs are recommended by travelers who have stayed in Wroclaw, Poland?
I'm Polish but have not stayed in Wroclaw overnight. In case you don't get many responses (I suspect you won't, as most Americans don't go there or know about it), take a look at www.booking.com - I'm sure you can find hotels at every price point. Poland in general is not very expensive and your dollar will go far, although you'll certainly find some expensive business and boutique properties there.
A good source of information for places formerly behind the Iron Curtain is In Your Pocket. They have info on their website, you can dowload their guides as PDF's, and you can get the guides on paper for free in the city itself.
Here's their Wroclaw page - note the "Stay And Sleep" tab on the left: http://www.inyourpocket.com/wroclaw
