Query: This product contains BPA - find a different yogurtmaker!

I bought this yogurt maker 2 1/2 years ago and used it regularly. However, when the recent BPA scare came out, I contacted the company to ask if it contains BPA. At first they did not respond to me at all. When I tried again, they sent me a ridiculous boilerplate message about how the US gov't does not see BPA as being dangerous. I would strongly recommend using a non-plastic yogurt maker (or at least one that doesn't contain BPA, as the chemical especially leaches into food when heated, and the whole point of a yogurt maker is to incubate the yogurt at the proper temperature) rather than risking exposing your family to more of this chemical than they have already gotten. It's upsetting to think I was doing something healthy for my sons by making them homemade yogurt instead of the storebought find, only to learn that they were exposed to extra bpa because of this maker. I am using the glass jar method now.
