I'm in the market for an EPROM burner and as directed here, i went to www.willem.org and Sivava. Willem seems to be plastered with messages from angry customers that they never received their orders. And Sivava won't return my email questions about products and shipping. Any corroboration on whether these companies are to be trusted or not would be appreciated. Maybe i should just go on ebay? If so, what should i look for or avoid (brands, countries of origin, tech specs, etc.) ?
