Yogurt Maker Question Please?

Hi I am suffering from Candida problems and want to try the fermented food approach. I also want to make my own kifer yogurt. I have seen a small yogurt maker which I can get from where I live in the UK and also the company sell packets of Kifer so this would be ideal for me. The only problem seems to be that the yogurt maker is made from plastic. This would not be so much of a problem if it were only the out side but it looks like it would be on the inside also. The thing is that I now also suffer from endometriosis, this means that I should avoid all plastic containers that have been heated up. Is there a way of getting a round this, does anyone know? I know that there are probably ways of doing the yogurt with out a maker, but I know that I would be more likely to do it if I had a maker. Can you buy glass jars that can be placed inside these makers?

Thanks Moonie
