Hi again.
Thanks a lot for the info, specially the T62+ was a great addition, I found it on banggood.com for exactly the same price i was going to pay for the T62 here in Spain.
After a little of research It seems to be a little of confusion though about if it has for sure a Carta screen or not (in the wiki of this site is listed as having a Pearl screen!:

Thanks!
