For what is is (a small computer store, and one of a chain) Fortune Computer is quite good. The selection, service and prices are great, and a bit better than Future Shop or Best Buy. The staff are quite helpful when needed, the store's located in a great place (College and Spadina) and it even has parking. All of the parts for my computer were bought here, as was the external hard drive I bought today at 4:30 in the afternoon today (July 15).
All in all, a good place to buy a computer and computer parts.
