[+Rep] iPhone 4 Charger?

I use to have this charger for my ipod and started using it for my iPhone 4, it stopped charging my iphone last night and I am in great need of a new one. I was going to buy the same one but I read reviews that it melted the charger casing so I am staying well away from that! I did get a plug for my current iPhone but I like to leave one at each of my parents house so I am not trailing it away with me.

I'm not exactly wanting to pay around £25 for a new iPhone plug so can anyone suggest a new, reliable, safe iPhone charger without the hefty price?

+Rep for all good answers! :D

I don't mean to sound rude but instead of creating a thread and writing a paragraph on the matter, couldn't you just search "IPHONE CHARGER" on Amazon :/

I have and I am a little uncertain which one to buy and as a forum is about peoples opinions I thought I would post and see if anyone recommends any! Thanks for your concern though :)
