Ok, I'll go against the grain and tell you that I love my Avent bottle wamer. Lots of temp control, never overheated, and you don't have to stand there replacing water to keep frozen milk defrosting...especially important if baby is screaming. A little pricey, but you may see them at mother's sales. I saw one once for five dollars and am kicking myself for talking another mom to be into it...I wouldn't have minded having a spare at that price.
Good luck!
