Anyone using LG dLite GD570 or Lollipop GD580?

I am thinking about buiyng unlocked LG phone and I wonder which one is better. It looks kinda the same and the only big difference I see is in camera resolution. Which one do you recommend, Lollipop or dLite GD570? Do you know where I can get it online (worldwide shipping) for reasonable price - I am not gonna get a contract with any network as I live in Poland and no network has this mobiles. I just need to buy unlocked phone and use it with my current T-mobile sim card. Is 134 $ on Amazon a good price? I found one for 80$ but it seems like a scam...too cheap for a new phone?
