My only other tip wold be, you get what you pay for. I've seen a lot of these cheapies get bad reviews because of inconsistent quality control. In a batch of 1000, five hundred are going to work great. Well, not great. They'll work with the promised low-frills features. If you get one of the others with one of 500 problems, you're still going to have a 50/50 shot of getting a problem even if you return it.
