Should i get iphone 5s or wait for iphone 6? - 1

I was initially going to get 5c but then my dads friend was selling one new 16gb in silver (the colour i wanted) for £380 with a full apple guarantee and my dad said max price is £410 he would spend (normally £10 for shipping) should i wait or should i go for it and if i got it i would have £30 spare thanks

Depends how long you want to wait, I would just get 5S as thats a great phone
