ghd's or alternative ceramic hair straighteners

Hi just recently my ghd's literally had sparks flying out, I know it really cheesed me off as I cant live without them. But I sent them back to ghd and they sent me a letter back saying that they can be repaired for £23.00 which is fine. Just wanted to know are other ceramic hair straighteners the cheaper alternative are just as good as ghd's. Just wanted to know out of interest.
