My first beer kit from Boots in England was a tin kit in a barrel and 12 plastic bottles (pet) just like small coke bottles but brown. In England we have comecial brewers that sell there products in them in supermarkets, 2 Litre and brown plastic.
They keep their head just as good as crown caped glass bottles. But if you intend to keep the beer for any length of time in clear pet bottles do keep it in a dark place. Check the caps for damage and don't over charge the bottles with sugar. Remember to keep everything sterile.
