I would say stick with Tannens. Not only will you find what you need but the people there are super helpful and nice. They really have a genuine love for magic. I dont really care for Ronjo's though. I used to go there before I started to go to Tannens. Now I take a train into the city when I want something specific. I dont know to me Ronjo's seems a bit over priced at times. And I don't really feel comfortable shopping there. I feel like its a buy something or get out kind of place. And he makes a habit of bashing on T11 a lot. Which isn't really cool.
